Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601254, here are decompositions:

431 + 31600823 = 31601254
521 + 31600733 = 31601254
743 + 31600511 = 31601254
761 + 31600493 = 31601254
947 + 31600307 = 31601254
953 + 31600301 = 31601254
977 + 31600277 = 31601254
1061 + 31600193 = 31601254

Showing the first eight; more decompositions exist.
