Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601434, here are decompositions:

17 + 31601417 = 31601434
23 + 31601411 = 31601434
41 + 31601393 = 31601434
167 + 31601267 = 31601434
383 + 31601051 = 31601434
617 + 31600817 = 31601434
701 + 31600733 = 31601434
911 + 31600523 = 31601434

Showing the first eight; more decompositions exist.
