Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600688, here are decompositions:

19 + 31600669 = 31600688
139 + 31600549 = 31600688
157 + 31600531 = 31600688
241 + 31600447 = 31600688
331 + 31600357 = 31600688
397 + 31600291 = 31600688
409 + 31600279 = 31600688
487 + 31600201 = 31600688

Showing the first eight; more decompositions exist.
