Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552744, here are decompositions:

11 + 31552733 = 31552744
17 + 31552727 = 31552744
23 + 31552721 = 31552744
101 + 31552643 = 31552744
191 + 31552553 = 31552744
257 + 31552487 = 31552744
491 + 31552253 = 31552744
617 + 31552127 = 31552744

Showing the first eight; more decompositions exist.
