Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472276, here are decompositions:

37 + 31472239 = 31472276
67 + 31472209 = 31472276
97 + 31472179 = 31472276
109 + 31472167 = 31472276
127 + 31472149 = 31472276
223 + 31472053 = 31472276
337 + 31471939 = 31472276
613 + 31471663 = 31472276

Showing the first eight; more decompositions exist.
