Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453318, here are decompositions:

137 + 31453181 = 31453318
467 + 31452851 = 31453318
569 + 31452749 = 31453318
587 + 31452731 = 31453318
599 + 31452719 = 31453318
641 + 31452677 = 31453318
719 + 31452599 = 31453318
797 + 31452521 = 31453318

Showing the first eight; more decompositions exist.
