Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590038, here are decompositions:

31 + 31590007 = 31590038
61 + 31589977 = 31590038
211 + 31589827 = 31590038
307 + 31589731 = 31590038
331 + 31589707 = 31590038
379 + 31589659 = 31590038
499 + 31589539 = 31590038
577 + 31589461 = 31590038

Showing the first eight; more decompositions exist.
