Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477350, here are decompositions:

29 + 31477321 = 31477350
59 + 31477291 = 31477350
61 + 31477289 = 31477350
137 + 31477213 = 31477350
239 + 31477111 = 31477350
251 + 31477099 = 31477350
271 + 31477079 = 31477350
283 + 31477067 = 31477350

Showing the first eight; more decompositions exist.
