Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552862, here are decompositions:

31 + 31552831 = 31552862
181 + 31552681 = 31552862
223 + 31552639 = 31552862
241 + 31552621 = 31552862
283 + 31552579 = 31552862
373 + 31552489 = 31552862
433 + 31552429 = 31552862
829 + 31552033 = 31552862

Showing the first eight; more decompositions exist.
