Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448884, here are decompositions:

167 + 31448717 = 31448884
191 + 31448693 = 31448884
263 + 31448621 = 31448884
281 + 31448603 = 31448884
461 + 31448423 = 31448884
503 + 31448381 = 31448884
563 + 31448321 = 31448884
587 + 31448297 = 31448884

Showing the first eight; more decompositions exist.
