Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449254, here are decompositions:

7 + 31449247 = 31449254
13 + 31449241 = 31449254
127 + 31449127 = 31449254
211 + 31449043 = 31449254
433 + 31448821 = 31449254
541 + 31448713 = 31449254
547 + 31448707 = 31449254
607 + 31448647 = 31449254

Showing the first eight; more decompositions exist.
