Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448526, here are decompositions:

7 + 31448519 = 31448526
19 + 31448507 = 31448526
47 + 31448479 = 31448526
79 + 31448447 = 31448526
103 + 31448423 = 31448526
113 + 31448413 = 31448526
149 + 31448377 = 31448526
157 + 31448369 = 31448526

Showing the first eight; more decompositions exist.
