Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601344, here are decompositions:

3 + 31601341 = 31601344
293 + 31601051 = 31601344
461 + 31600883 = 31601344
521 + 31600823 = 31601344
641 + 31600703 = 31601344
821 + 31600523 = 31601344
1151 + 31600193 = 31601344
1187 + 31600157 = 31601344

Showing the first eight; more decompositions exist.
