Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747042, here are decompositions:

  • 43 + 8746999 = 8747042
  • 79 + 8746963 = 8747042
  • 103 + 8746939 = 8747042
  • 163 + 8746879 = 8747042
  • 181 + 8746861 = 8747042
  • 193 + 8746849 = 8747042
  • 223 + 8746819 = 8747042
  • 229 + 8746813 = 8747042

Showing the first eight; more decompositions exist.
