Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449974, here are decompositions:

7 + 31449967 = 31449974
37 + 31449937 = 31449974
43 + 31449931 = 31449974
103 + 31449871 = 31449974
151 + 31449823 = 31449974
223 + 31449751 = 31449974
277 + 31449697 = 31449974
337 + 31449637 = 31449974

Showing the first eight; more decompositions exist.
