Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540948, here are decompositions:

239 + 31540709 = 31540948
269 + 31540679 = 31540948
311 + 31540637 = 31540948
317 + 31540631 = 31540948
419 + 31540529 = 31540948
449 + 31540499 = 31540948
839 + 31540109 = 31540948
941 + 31540007 = 31540948

Showing the first eight; more decompositions exist.
