Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448598, here are decompositions:

11 + 31448587 = 31448598
17 + 31448581 = 31448598
19 + 31448579 = 31448598
47 + 31448551 = 31448598
79 + 31448519 = 31448598
149 + 31448449 = 31448598
151 + 31448447 = 31448598
229 + 31448369 = 31448598

Showing the first eight; more decompositions exist.
