Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448764, here are decompositions:

23 + 31448741 = 31448764
47 + 31448717 = 31448764
71 + 31448693 = 31448764
257 + 31448507 = 31448764
317 + 31448447 = 31448764
383 + 31448381 = 31448764
443 + 31448321 = 31448764
461 + 31448303 = 31448764

Showing the first eight; more decompositions exist.
