Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615190, here are decompositions:

  • 13 + 8615177 = 8615190
  • 29 + 8615161 = 8615190
  • 41 + 8615149 = 8615190
  • 53 + 8615137 = 8615190
  • 107 + 8615083 = 8615190
  • 127 + 8615063 = 8615190
  • 139 + 8615051 = 8615190
  • 173 + 8615017 = 8615190

Showing the first eight; more decompositions exist.
