Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601574, here are decompositions:

5 + 31601569 = 31601574
7 + 31601567 = 31601574
23 + 31601551 = 31601574
47 + 31601527 = 31601574
61 + 31601513 = 31601574
101 + 31601473 = 31601574
157 + 31601417 = 31601574
163 + 31601411 = 31601574

Showing the first eight; more decompositions exist.
