Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601502, here are decompositions:

13 + 31601489 = 31601502
29 + 31601473 = 31601502
109 + 31601393 = 31601502
239 + 31601263 = 31601502
311 + 31601191 = 31601502
419 + 31601083 = 31601502
461 + 31601041 = 31601502
479 + 31601023 = 31601502

Showing the first eight; more decompositions exist.
