Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493548, here are decompositions:

29 + 31493519 = 31493548
71 + 31493477 = 31493548
101 + 31493447 = 31493548
227 + 31493321 = 31493548
257 + 31493291 = 31493548
347 + 31493201 = 31493548
479 + 31493069 = 31493548
491 + 31493057 = 31493548

Showing the first eight; more decompositions exist.
