Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479848, here are decompositions:

19 + 31479829 = 31479848
31 + 31479817 = 31479848
79 + 31479769 = 31479848
109 + 31479739 = 31479848
151 + 31479697 = 31479848
199 + 31479649 = 31479848
229 + 31479619 = 31479848
271 + 31479577 = 31479848

Showing the first eight; more decompositions exist.
