Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477294, here are decompositions:

3 + 31477291 = 31477294
5 + 31477289 = 31477294
113 + 31477181 = 31477294
131 + 31477163 = 31477294
227 + 31477067 = 31477294
347 + 31476947 = 31477294
683 + 31476611 = 31477294
701 + 31476593 = 31477294

Showing the first eight; more decompositions exist.
