Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501246, here are decompositions:

17 + 31501229 = 31501246
47 + 31501199 = 31501246
269 + 31500977 = 31501246
347 + 31500899 = 31501246
383 + 31500863 = 31501246
449 + 31500797 = 31501246
479 + 31500767 = 31501246
509 + 31500737 = 31501246

Showing the first eight; more decompositions exist.
