Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454546, here are decompositions:

157 + 31454389 = 31454546
163 + 31454383 = 31454546
283 + 31454263 = 31454546
349 + 31454197 = 31454546
397 + 31454149 = 31454546
463 + 31454083 = 31454546
523 + 31454023 = 31454546
577 + 31453969 = 31454546

Showing the first eight; more decompositions exist.
