Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574276, here are decompositions:

43 + 31574233 = 31574276
73 + 31574203 = 31574276
103 + 31574173 = 31574276
229 + 31574047 = 31574276
277 + 31573999 = 31574276
457 + 31573819 = 31574276
523 + 31573753 = 31574276
883 + 31573393 = 31574276

Showing the first eight; more decompositions exist.
