Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601516, here are decompositions:

3 + 31601513 = 31601516
7 + 31601509 = 31601516
43 + 31601473 = 31601516
109 + 31601407 = 31601516
157 + 31601359 = 31601516
313 + 31601203 = 31601516
337 + 31601179 = 31601516
379 + 31601137 = 31601516

Showing the first eight; more decompositions exist.
