Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448962, here are decompositions:

53 + 31448909 = 31448962
59 + 31448903 = 31448962
71 + 31448891 = 31448962
263 + 31448699 = 31448962
269 + 31448693 = 31448962
359 + 31448603 = 31448962
383 + 31448579 = 31448962
443 + 31448519 = 31448962

Showing the first eight; more decompositions exist.
