Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618162, here are decompositions:

  • 13 + 8618149 = 8618162
  • 31 + 8618131 = 8618162
  • 43 + 8618119 = 8618162
  • 73 + 8618089 = 8618162
  • 79 + 8618083 = 8618162
  • 103 + 8618059 = 8618162
  • 229 + 8617933 = 8618162
  • 409 + 8617753 = 8618162

Showing the first eight; more decompositions exist.
