Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448762, here are decompositions:

43 + 31448719 = 31448762
181 + 31448581 = 31448762
211 + 31448551 = 31448762
229 + 31448533 = 31448762
283 + 31448479 = 31448762
313 + 31448449 = 31448762
349 + 31448413 = 31448762
439 + 31448323 = 31448762

Showing the first eight; more decompositions exist.
