Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501432, here are decompositions:

5 + 31501427 = 31501432
23 + 31501409 = 31501432
29 + 31501403 = 31501432
71 + 31501361 = 31501432
101 + 31501331 = 31501432
233 + 31501199 = 31501432
491 + 31500941 = 31501432
509 + 31500923 = 31501432

Showing the first eight; more decompositions exist.
