Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448698, here are decompositions:

5 + 31448693 = 31448698
59 + 31448639 = 31448698
179 + 31448519 = 31448698
191 + 31448507 = 31448698
251 + 31448447 = 31448698
317 + 31448381 = 31448698
389 + 31448309 = 31448698
401 + 31448297 = 31448698

Showing the first eight; more decompositions exist.
