Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454826, here are decompositions:

17 + 31454809 = 31454826
43 + 31454783 = 31454826
89 + 31454737 = 31454826
157 + 31454669 = 31454826
173 + 31454653 = 31454826
199 + 31454627 = 31454826
239 + 31454587 = 31454826
313 + 31454513 = 31454826

Showing the first eight; more decompositions exist.
