Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476266, here are decompositions:

79 + 31476187 = 31476266
97 + 31476169 = 31476266
109 + 31476157 = 31476266
193 + 31476073 = 31476266
313 + 31475953 = 31476266
337 + 31475929 = 31476266
439 + 31475827 = 31476266
487 + 31475779 = 31476266

Showing the first eight; more decompositions exist.
