Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577684, here are decompositions:

37 + 31577647 = 31577684
97 + 31577587 = 31577684
157 + 31577527 = 31577684
163 + 31577521 = 31577684
211 + 31577473 = 31577684
283 + 31577401 = 31577684
331 + 31577353 = 31577684
421 + 31577263 = 31577684

Showing the first eight; more decompositions exist.
