Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677242, here are decompositions:

  • 19 + 8677223 = 8677242
  • 61 + 8677181 = 8677242
  • 71 + 8677171 = 8677242
  • 103 + 8677139 = 8677242
  • 163 + 8677079 = 8677242
  • 191 + 8677051 = 8677242
  • 199 + 8677043 = 8677242
  • 251 + 8676991 = 8677242

Showing the first eight; more decompositions exist.
