Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501042, here are decompositions:

  • 61 + 2147500981 = 2147501042
  • 163 + 2147500879 = 2147501042
  • 229 + 2147500813 = 2147501042
  • 691 + 2147500351 = 2147501042
  • 859 + 2147500183 = 2147501042
  • 919 + 2147500123 = 2147501042
  • 1201 + 2147499841 = 2147501042
  • 1213 + 2147499829 = 2147501042

Showing the first eight; more decompositions exist.
