Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468144, here are decompositions:

47 + 31468097 = 31468144
131 + 31468013 = 31468144
233 + 31467911 = 31468144
251 + 31467893 = 31468144
467 + 31467677 = 31468144
557 + 31467587 = 31468144
593 + 31467551 = 31468144
641 + 31467503 = 31468144

Showing the first eight; more decompositions exist.
