Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601412, here are decompositions:

5 + 31601407 = 31601412
19 + 31601393 = 31601412
53 + 31601359 = 31601412
71 + 31601341 = 31601412
149 + 31601263 = 31601412
233 + 31601179 = 31601412
313 + 31601099 = 31601412
389 + 31601023 = 31601412

Showing the first eight; more decompositions exist.
