Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552974, here are decompositions:

31 + 31552943 = 31552974
67 + 31552907 = 31552974
83 + 31552891 = 31552974
127 + 31552847 = 31552974
157 + 31552817 = 31552974
227 + 31552747 = 31552974
241 + 31552733 = 31552974
281 + 31552693 = 31552974

Showing the first eight; more decompositions exist.
