Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978488, here are decompositions:

  • 31 + 978457 = 978488
  • 61 + 978427 = 978488
  • 139 + 978349 = 978488
  • 151 + 978337 = 978488
  • 211 + 978277 = 978488
  • 271 + 978217 = 978488
  • 307 + 978181 = 978488
  • 331 + 978157 = 978488

Showing the first eight; more decompositions exist.
