Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147507284, here are decompositions:

  • 5 + 2147507279 = 2147507284
  • 11 + 2147507273 = 2147507284
  • 173 + 2147507111 = 2147507284
  • 257 + 2147507027 = 2147507284
  • 353 + 2147506931 = 2147507284
  • 401 + 2147506883 = 2147507284
  • 431 + 2147506853 = 2147507284
  • 521 + 2147506763 = 2147507284

Showing the first eight; more decompositions exist.
