Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463282, here are decompositions:

13 + 31463269 = 31463282
79 + 31463203 = 31463282
199 + 31463083 = 31463282
313 + 31462969 = 31463282
349 + 31462933 = 31463282
373 + 31462909 = 31463282
523 + 31462759 = 31463282
673 + 31462609 = 31463282

Showing the first eight; more decompositions exist.
