Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506236, here are decompositions:

43 + 31506193 = 31506236
277 + 31505959 = 31506236
313 + 31505923 = 31506236
499 + 31505737 = 31506236
577 + 31505659 = 31506236
613 + 31505623 = 31506236
709 + 31505527 = 31506236
877 + 31505359 = 31506236

Showing the first eight; more decompositions exist.
