Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600580, here are decompositions:

31 + 31600549 = 31600580
127 + 31600453 = 31600580
139 + 31600441 = 31600580
157 + 31600423 = 31600580
223 + 31600357 = 31600580
307 + 31600273 = 31600580
379 + 31600201 = 31600580
463 + 31600117 = 31600580

Showing the first eight; more decompositions exist.
