Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600394, here are decompositions:

37 + 31600357 = 31600394
61 + 31600333 = 31600394
103 + 31600291 = 31600394
193 + 31600201 = 31600394
277 + 31600117 = 31600394
307 + 31600087 = 31600394
337 + 31600057 = 31600394
523 + 31599871 = 31600394

Showing the first eight; more decompositions exist.
