Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601304, here are decompositions:

37 + 31601267 = 31601304
41 + 31601263 = 31601304
101 + 31601203 = 31601304
113 + 31601191 = 31601304
167 + 31601137 = 31601304
227 + 31601077 = 31601304
263 + 31601041 = 31601304
281 + 31601023 = 31601304

Showing the first eight; more decompositions exist.
