Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540366, here are decompositions:

3 + 31540363 = 31540366
23 + 31540343 = 31540366
149 + 31540217 = 31540366
257 + 31540109 = 31540366
353 + 31540013 = 31540366
359 + 31540007 = 31540366
503 + 31539863 = 31540366
509 + 31539857 = 31540366

Showing the first eight; more decompositions exist.
