Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610764, here are decompositions:

23 + 31610741 = 31610764
41 + 31610723 = 31610764
191 + 31610573 = 31610764
401 + 31610363 = 31610764
431 + 31610333 = 31610764
593 + 31610171 = 31610764
683 + 31610081 = 31610764
701 + 31610063 = 31610764

Showing the first eight; more decompositions exist.
