Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475092, here are decompositions:

3 + 31475089 = 31475092
23 + 31475069 = 31475092
83 + 31475009 = 31475092
263 + 31474829 = 31475092
359 + 31474733 = 31475092
401 + 31474691 = 31475092
419 + 31474673 = 31475092
491 + 31474601 = 31475092

Showing the first eight; more decompositions exist.
