Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448694, here are decompositions:

47 + 31448647 = 31448694
73 + 31448621 = 31448694
107 + 31448587 = 31448694
113 + 31448581 = 31448694
271 + 31448423 = 31448694
281 + 31448413 = 31448694
313 + 31448381 = 31448694
317 + 31448377 = 31448694

Showing the first eight; more decompositions exist.
