Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448834, here are decompositions:

13 + 31448821 = 31448834
31 + 31448803 = 31448834
127 + 31448707 = 31448834
283 + 31448551 = 31448834
421 + 31448413 = 31448834
457 + 31448377 = 31448834
541 + 31448293 = 31448834
601 + 31448233 = 31448834

Showing the first eight; more decompositions exist.
