Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448908, here are decompositions:

5 + 31448903 = 31448908
11 + 31448897 = 31448908
17 + 31448891 = 31448908
167 + 31448741 = 31448908
191 + 31448717 = 31448908
269 + 31448639 = 31448908
389 + 31448519 = 31448908
401 + 31448507 = 31448908

Showing the first eight; more decompositions exist.
