Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448604, here are decompositions:

17 + 31448587 = 31448604
23 + 31448581 = 31448604
53 + 31448551 = 31448604
71 + 31448533 = 31448604
97 + 31448507 = 31448604
157 + 31448447 = 31448604
181 + 31448423 = 31448604
191 + 31448413 = 31448604

Showing the first eight; more decompositions exist.
