Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454436, here are decompositions:

5 + 31454431 = 31454436
47 + 31454389 = 31454436
53 + 31454383 = 31454436
59 + 31454377 = 31454436
173 + 31454263 = 31454436
239 + 31454197 = 31454436
313 + 31454123 = 31454436
353 + 31454083 = 31454436

Showing the first eight; more decompositions exist.
