Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471332, here are decompositions:

43 + 31471289 = 31471332
223 + 31471109 = 31471332
239 + 31471093 = 31471332
241 + 31471091 = 31471332
281 + 31471051 = 31471332
331 + 31471001 = 31471332
379 + 31470953 = 31471332
419 + 31470913 = 31471332

Showing the first eight; more decompositions exist.
