Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454414, here are decompositions:

31 + 31454383 = 31454414
37 + 31454377 = 31454414
151 + 31454263 = 31454414
193 + 31454221 = 31454414
223 + 31454191 = 31454414
331 + 31454083 = 31454414
337 + 31454077 = 31454414
421 + 31453993 = 31454414

Showing the first eight; more decompositions exist.
