Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600442, here are decompositions:

19 + 31600423 = 31600442
109 + 31600333 = 31600442
151 + 31600291 = 31600442
163 + 31600279 = 31600442
241 + 31600201 = 31600442
541 + 31599901 = 31600442
571 + 31599871 = 31600442
619 + 31599823 = 31600442

Showing the first eight; more decompositions exist.
