Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480366, here are decompositions:

17 + 31480349 = 31480366
107 + 31480259 = 31480366
263 + 31480103 = 31480366
317 + 31480049 = 31480366
347 + 31480019 = 31480366
419 + 31479947 = 31480366
509 + 31479857 = 31480366
563 + 31479803 = 31480366

Showing the first eight; more decompositions exist.
