Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552856, here are decompositions:

3 + 31552853 = 31552856
109 + 31552747 = 31552856
163 + 31552693 = 31552856
277 + 31552579 = 31552856
367 + 31552489 = 31552856
463 + 31552393 = 31552856
547 + 31552309 = 31552856
619 + 31552237 = 31552856

Showing the first eight; more decompositions exist.
