Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449316, here are decompositions:

29 + 31449287 = 31449316
53 + 31449263 = 31449316
83 + 31449233 = 31449316
137 + 31449179 = 31449316
233 + 31449083 = 31449316
263 + 31449053 = 31449316
419 + 31448897 = 31449316
599 + 31448717 = 31449316

Showing the first eight; more decompositions exist.
