Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601246, here are decompositions:

43 + 31601203 = 31601246
67 + 31601179 = 31601246
109 + 31601137 = 31601246
163 + 31601083 = 31601246
223 + 31601023 = 31601246
277 + 31600969 = 31601246
463 + 31600783 = 31601246
577 + 31600669 = 31601246

Showing the first eight; more decompositions exist.
