Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449024, here are decompositions:

7 + 31449017 = 31449024
37 + 31448987 = 31449024
127 + 31448897 = 31449024
283 + 31448741 = 31449024
307 + 31448717 = 31449024
311 + 31448713 = 31449024
317 + 31448707 = 31449024
331 + 31448693 = 31449024

Showing the first eight; more decompositions exist.
