Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147588190, here are decompositions:

  • 23 + 2147588167 = 2147588190
  • 37 + 2147588153 = 2147588190
  • 67 + 2147588123 = 2147588190
  • 73 + 2147588117 = 2147588190
  • 101 + 2147588089 = 2147588190
  • 149 + 2147588041 = 2147588190
  • 157 + 2147588033 = 2147588190
  • 173 + 2147588017 = 2147588190

Showing the first eight; more decompositions exist.
