Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600562, here are decompositions:

13 + 31600549 = 31600562
31 + 31600531 = 31600562
109 + 31600453 = 31600562
139 + 31600423 = 31600562
229 + 31600333 = 31600562
271 + 31600291 = 31600562
283 + 31600279 = 31600562
373 + 31600189 = 31600562

Showing the first eight; more decompositions exist.
