Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448968, here are decompositions:

59 + 31448909 = 31448968
71 + 31448897 = 31448968
227 + 31448741 = 31448968
251 + 31448717 = 31448968
269 + 31448699 = 31448968
347 + 31448621 = 31448968
389 + 31448579 = 31448968
449 + 31448519 = 31448968

Showing the first eight; more decompositions exist.
