Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473190, here are decompositions:

  • 3 + 2147473187 = 2147473190
  • 73 + 2147473117 = 2147473190
  • 307 + 2147472883 = 2147473190
  • 433 + 2147472757 = 2147473190
  • 439 + 2147472751 = 2147473190
  • 691 + 2147472499 = 2147473190
  • 769 + 2147472421 = 2147473190
  • 991 + 2147472199 = 2147473190

Showing the first eight; more decompositions exist.
