Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613782, here are decompositions:

113 + 31613669 = 31613782
269 + 31613513 = 31613782
383 + 31613399 = 31613782
449 + 31613333 = 31613782
491 + 31613291 = 31613782
821 + 31612961 = 31613782
929 + 31612853 = 31613782
1049 + 31612733 = 31613782

Showing the first eight; more decompositions exist.
