Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448964, here are decompositions:

61 + 31448903 = 31448964
67 + 31448897 = 31448964
73 + 31448891 = 31448964
101 + 31448863 = 31448964
223 + 31448741 = 31448964
251 + 31448713 = 31448964
257 + 31448707 = 31448964
271 + 31448693 = 31448964

Showing the first eight; more decompositions exist.
