Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601542, here are decompositions:

3 + 31601539 = 31601542
29 + 31601513 = 31601542
53 + 31601489 = 31601542
131 + 31601411 = 31601542
149 + 31601393 = 31601542
443 + 31601099 = 31601542
491 + 31601051 = 31601542
659 + 31600883 = 31601542

Showing the first eight; more decompositions exist.
