Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454618, here are decompositions:

31 + 31454587 = 31454618
157 + 31454461 = 31454618
229 + 31454389 = 31454618
241 + 31454377 = 31454618
397 + 31454221 = 31454618
421 + 31454197 = 31454618
457 + 31454161 = 31454618
541 + 31454077 = 31454618

Showing the first eight; more decompositions exist.
