Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601770, here are decompositions:

3 + 31601767 = 31601770
47 + 31601723 = 31601770
59 + 31601711 = 31601770
71 + 31601699 = 31601770
257 + 31601513 = 31601770
281 + 31601489 = 31601770
353 + 31601417 = 31601770
359 + 31601411 = 31601770

Showing the first eight; more decompositions exist.
