Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552848, here are decompositions:

17 + 31552831 = 31552848
31 + 31552817 = 31552848
101 + 31552747 = 31552848
127 + 31552721 = 31552848
139 + 31552709 = 31552848
167 + 31552681 = 31552848
227 + 31552621 = 31552848
269 + 31552579 = 31552848

Showing the first eight; more decompositions exist.
