Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448734, here are decompositions:

17 + 31448717 = 31448734
41 + 31448693 = 31448734
113 + 31448621 = 31448734
131 + 31448603 = 31448734
227 + 31448507 = 31448734
311 + 31448423 = 31448734
353 + 31448381 = 31448734
431 + 31448303 = 31448734

Showing the first eight; more decompositions exist.
