Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552758, here are decompositions:

11 + 31552747 = 31552758
31 + 31552727 = 31552758
37 + 31552721 = 31552758
137 + 31552621 = 31552758
179 + 31552579 = 31552758
269 + 31552489 = 31552758
271 + 31552487 = 31552758
337 + 31552421 = 31552758

Showing the first eight; more decompositions exist.
