Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601524, here are decompositions:

11 + 31601513 = 31601524
107 + 31601417 = 31601524
113 + 31601411 = 31601524
131 + 31601393 = 31601524
167 + 31601357 = 31601524
257 + 31601267 = 31601524
641 + 31600883 = 31601524
701 + 31600823 = 31601524

Showing the first eight; more decompositions exist.
