Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637248, here are decompositions:

  • 97 + 8637151 = 8637248
  • 157 + 8637091 = 8637248
  • 181 + 8637067 = 8637248
  • 241 + 8637007 = 8637248
  • 331 + 8636917 = 8637248
  • 337 + 8636911 = 8637248
  • 349 + 8636899 = 8637248
  • 379 + 8636869 = 8637248

Showing the first eight; more decompositions exist.
