Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601510, here are decompositions:

37 + 31601473 = 31601510
103 + 31601407 = 31601510
151 + 31601359 = 31601510
163 + 31601347 = 31601510
307 + 31601203 = 31601510
331 + 31601179 = 31601510
373 + 31601137 = 31601510
433 + 31601077 = 31601510

Showing the first eight; more decompositions exist.
