Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449248, here are decompositions:

7 + 31449241 = 31449248
211 + 31449037 = 31449248
349 + 31448899 = 31449248
409 + 31448839 = 31449248
541 + 31448707 = 31449248
601 + 31448647 = 31449248
661 + 31448587 = 31449248
769 + 31448479 = 31449248

Showing the first eight; more decompositions exist.
