Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613764, here are decompositions:

47 + 31613717 = 31613764
137 + 31613627 = 31613764
251 + 31613513 = 31613764
353 + 31613411 = 31613764
431 + 31613333 = 31613764
521 + 31613243 = 31613764
593 + 31613171 = 31613764
647 + 31613117 = 31613764

Showing the first eight; more decompositions exist.
