Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552774, here are decompositions:

41 + 31552733 = 31552774
47 + 31552727 = 31552774
53 + 31552721 = 31552774
131 + 31552643 = 31552774
353 + 31552421 = 31552774
503 + 31552271 = 31552774
521 + 31552253 = 31552774
563 + 31552211 = 31552774

Showing the first eight; more decompositions exist.
