Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467862, here are decompositions:

  • 61 + 2147467801 = 2147467862
  • 103 + 2147467759 = 2147467862
  • 151 + 2147467711 = 2147467862
  • 193 + 2147467669 = 2147467862
  • 223 + 2147467639 = 2147467862
  • 283 + 2147467579 = 2147467862
  • 523 + 2147467339 = 2147467862
  • 541 + 2147467321 = 2147467862

Showing the first eight; more decompositions exist.
