Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661382, here are decompositions:

  • 29 + 8661353 = 8661382
  • 71 + 8661311 = 8661382
  • 101 + 8661281 = 8661382
  • 131 + 8661251 = 8661382
  • 179 + 8661203 = 8661382
  • 263 + 8661119 = 8661382
  • 293 + 8661089 = 8661382
  • 449 + 8660933 = 8661382

Showing the first eight; more decompositions exist.
