Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601492, here are decompositions:

3 + 31601489 = 31601492
19 + 31601473 = 31601492
151 + 31601341 = 31601492
229 + 31601263 = 31601492
313 + 31601179 = 31601492
409 + 31601083 = 31601492
499 + 31600993 = 31601492
523 + 31600969 = 31601492

Showing the first eight; more decompositions exist.
