Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474276, here are decompositions:

23 + 31474253 = 31474276
59 + 31474217 = 31474276
233 + 31474043 = 31474276
269 + 31474007 = 31474276
359 + 31473917 = 31474276
389 + 31473887 = 31474276
467 + 31473809 = 31474276
569 + 31473707 = 31474276

Showing the first eight; more decompositions exist.
