Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747286, here are decompositions:

  • 13 + 8747273 = 8747286
  • 29 + 8747257 = 8747286
  • 43 + 8747243 = 8747286
  • 73 + 8747213 = 8747286
  • 127 + 8747159 = 8747286
  • 167 + 8747119 = 8747286
  • 193 + 8747093 = 8747286
  • 307 + 8746979 = 8747286

Showing the first eight; more decompositions exist.
