Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449104, here are decompositions:

61 + 31449043 = 31449104
67 + 31449037 = 31449104
241 + 31448863 = 31449104
283 + 31448821 = 31449104
397 + 31448707 = 31449104
457 + 31448647 = 31449104
523 + 31448581 = 31449104
571 + 31448533 = 31449104

Showing the first eight; more decompositions exist.
