Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449610, here are decompositions:

29 + 31449581 = 31449610
41 + 31449569 = 31449610
53 + 31449557 = 31449610
83 + 31449527 = 31449610
131 + 31449479 = 31449610
233 + 31449377 = 31449610
251 + 31449359 = 31449610
347 + 31449263 = 31449610

Showing the first eight; more decompositions exist.
