Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727290, here are decompositions:

  • 3 + 8727287 = 8727290
  • 7 + 8727283 = 8727290
  • 43 + 8727247 = 8727290
  • 79 + 8727211 = 8727290
  • 127 + 8727163 = 8727290
  • 181 + 8727109 = 8727290
  • 199 + 8727091 = 8727290
  • 223 + 8727067 = 8727290

Showing the first eight; more decompositions exist.
