Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448746, here are decompositions:

5 + 31448741 = 31448746
29 + 31448717 = 31448746
47 + 31448699 = 31448746
53 + 31448693 = 31448746
107 + 31448639 = 31448746
167 + 31448579 = 31448746
227 + 31448519 = 31448746
239 + 31448507 = 31448746

Showing the first eight; more decompositions exist.
