Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449914, here are decompositions:

43 + 31449871 = 31449914
61 + 31449853 = 31449914
157 + 31449757 = 31449914
163 + 31449751 = 31449914
241 + 31449673 = 31449914
277 + 31449637 = 31449914
337 + 31449577 = 31449914
421 + 31449493 = 31449914

Showing the first eight; more decompositions exist.
