Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600154, here are decompositions:

37 + 31600117 = 31600154
67 + 31600087 = 31600154
97 + 31600057 = 31600154
241 + 31599913 = 31600154
277 + 31599877 = 31600154
283 + 31599871 = 31600154
331 + 31599823 = 31600154
373 + 31599781 = 31600154

Showing the first eight; more decompositions exist.
