Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613186, here are decompositions:

43 + 31613143 = 31613186
67 + 31613119 = 31613186
79 + 31613107 = 31613186
313 + 31612873 = 31613186
433 + 31612753 = 31613186
439 + 31612747 = 31613186
457 + 31612729 = 31613186
523 + 31612663 = 31613186

Showing the first eight; more decompositions exist.
