Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496380, here are decompositions:

11 + 31496369 = 31496380
59 + 31496321 = 31496380
239 + 31496141 = 31496380
257 + 31496123 = 31496380
281 + 31496099 = 31496380
353 + 31496027 = 31496380
401 + 31495979 = 31496380
431 + 31495949 = 31496380

Showing the first eight; more decompositions exist.
