Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448794, here are decompositions:

53 + 31448741 = 31448794
101 + 31448693 = 31448794
173 + 31448621 = 31448794
191 + 31448603 = 31448794
347 + 31448447 = 31448794
491 + 31448303 = 31448794
593 + 31448201 = 31448794
653 + 31448141 = 31448794

Showing the first eight; more decompositions exist.
