Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600358, here are decompositions:

67 + 31600291 = 31600358
79 + 31600279 = 31600358
157 + 31600201 = 31600358
241 + 31600117 = 31600358
271 + 31600087 = 31600358
457 + 31599901 = 31600358
487 + 31599871 = 31600358
499 + 31599859 = 31600358

Showing the first eight; more decompositions exist.
