Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509364, here are decompositions:

41 + 31509323 = 31509364
113 + 31509251 = 31509364
191 + 31509173 = 31509364
311 + 31509053 = 31509364
347 + 31509017 = 31509364
443 + 31508921 = 31509364
521 + 31508843 = 31509364
617 + 31508747 = 31509364

Showing the first eight; more decompositions exist.
