Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448706, here are decompositions:

7 + 31448699 = 31448706
13 + 31448693 = 31448706
59 + 31448647 = 31448706
67 + 31448639 = 31448706
103 + 31448603 = 31448706
127 + 31448579 = 31448706
173 + 31448533 = 31448706
199 + 31448507 = 31448706

Showing the first eight; more decompositions exist.
