Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475314, here are decompositions:

71 + 31475243 = 31475314
83 + 31475231 = 31475314
173 + 31475141 = 31475314
317 + 31474997 = 31475314
383 + 31474931 = 31475314
593 + 31474721 = 31475314
641 + 31474673 = 31475314
743 + 31474571 = 31475314

Showing the first eight; more decompositions exist.
