Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601090, here are decompositions:

7 + 31601083 = 31601090
13 + 31601077 = 31601090
67 + 31601023 = 31601090
97 + 31600993 = 31601090
229 + 31600861 = 31601090
307 + 31600783 = 31601090
337 + 31600753 = 31601090
349 + 31600741 = 31601090

Showing the first eight; more decompositions exist.
