Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499426, here are decompositions:

19 + 31499407 = 31499426
43 + 31499383 = 31499426
97 + 31499329 = 31499426
103 + 31499323 = 31499426
199 + 31499227 = 31499426
349 + 31499077 = 31499426
433 + 31498993 = 31499426
463 + 31498963 = 31499426

Showing the first eight; more decompositions exist.
