Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552824, here are decompositions:

7 + 31552817 = 31552824
97 + 31552727 = 31552824
103 + 31552721 = 31552824
131 + 31552693 = 31552824
181 + 31552643 = 31552824
271 + 31552553 = 31552824
337 + 31552487 = 31552824
421 + 31552403 = 31552824

Showing the first eight; more decompositions exist.
