Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454326, here are decompositions:

5 + 31454321 = 31454326
107 + 31454219 = 31454326
179 + 31454147 = 31454326
383 + 31453943 = 31454326
443 + 31453883 = 31454326
503 + 31453823 = 31454326
593 + 31453733 = 31454326
599 + 31453727 = 31454326

Showing the first eight; more decompositions exist.
