Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476718, here are decompositions:

107 + 31476611 = 31476718
131 + 31476587 = 31476718
167 + 31476551 = 31476718
257 + 31476461 = 31476718
269 + 31476449 = 31476718
281 + 31476437 = 31476718
347 + 31476371 = 31476718
401 + 31476317 = 31476718

Showing the first eight; more decompositions exist.
