Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577792, here are decompositions:

13 + 31577779 = 31577792
19 + 31577773 = 31577792
199 + 31577593 = 31577792
271 + 31577521 = 31577792
283 + 31577509 = 31577792
409 + 31577383 = 31577792
439 + 31577353 = 31577792
523 + 31577269 = 31577792

Showing the first eight; more decompositions exist.
