Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613890, here are decompositions:

  • 3 + 8613887 = 8613890
  • 37 + 8613853 = 8613890
  • 73 + 8613817 = 8613890
  • 79 + 8613811 = 8613890
  • 139 + 8613751 = 8613890
  • 151 + 8613739 = 8613890
  • 157 + 8613733 = 8613890
  • 331 + 8613559 = 8613890

Showing the first eight; more decompositions exist.
