Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600542, here are decompositions:

11 + 31600531 = 31600542
13 + 31600529 = 31600542
19 + 31600523 = 31600542
31 + 31600511 = 31600542
89 + 31600453 = 31600542
101 + 31600441 = 31600542
223 + 31600319 = 31600542
241 + 31600301 = 31600542

Showing the first eight; more decompositions exist.
