Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468282, here are decompositions:

11 + 31468271 = 31468282
23 + 31468259 = 31468282
59 + 31468223 = 31468282
71 + 31468211 = 31468282
113 + 31468169 = 31468282
269 + 31468013 = 31468282
281 + 31468001 = 31468282
383 + 31467899 = 31468282

Showing the first eight; more decompositions exist.
