Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448616, here are decompositions:

13 + 31448603 = 31448616
29 + 31448587 = 31448616
37 + 31448579 = 31448616
83 + 31448533 = 31448616
97 + 31448519 = 31448616
109 + 31448507 = 31448616
137 + 31448479 = 31448616
167 + 31448449 = 31448616

Showing the first eight; more decompositions exist.
