Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609814, here are decompositions:

37 + 31609777 = 31609814
73 + 31609741 = 31609814
283 + 31609531 = 31609814
421 + 31609393 = 31609814
433 + 31609381 = 31609814
547 + 31609267 = 31609814
601 + 31609213 = 31609814
727 + 31609087 = 31609814

Showing the first eight; more decompositions exist.
