Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448976, here are decompositions:

67 + 31448909 = 31448976
73 + 31448903 = 31448976
79 + 31448897 = 31448976
113 + 31448863 = 31448976
137 + 31448839 = 31448976
173 + 31448803 = 31448976
257 + 31448719 = 31448976
263 + 31448713 = 31448976

Showing the first eight; more decompositions exist.
