Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496080, here are decompositions:

23 + 31496057 = 31496080
53 + 31496027 = 31496080
101 + 31495979 = 31496080
131 + 31495949 = 31496080
233 + 31495847 = 31496080
347 + 31495733 = 31496080
389 + 31495691 = 31496080
419 + 31495661 = 31496080

Showing the first eight; more decompositions exist.
