Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468960, here are decompositions:

41 + 31468919 = 31468960
59 + 31468901 = 31468960
137 + 31468823 = 31468960
167 + 31468793 = 31468960
233 + 31468727 = 31468960
293 + 31468667 = 31468960
389 + 31468571 = 31468960
401 + 31468559 = 31468960

Showing the first eight; more decompositions exist.
