Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487042, here are decompositions:

  • 13 + 2147487029 = 2147487042
  • 61 + 2147486981 = 2147487042
  • 73 + 2147486969 = 2147487042
  • 163 + 2147486879 = 2147487042
  • 191 + 2147486851 = 2147487042
  • 193 + 2147486849 = 2147487042
  • 199 + 2147486843 = 2147487042
  • 223 + 2147486819 = 2147487042

Showing the first eight; more decompositions exist.
