Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450026, here are decompositions:

5 + 31450021 = 31450026
37 + 31449989 = 31450026
59 + 31449967 = 31450026
89 + 31449937 = 31450026
103 + 31449923 = 31450026
173 + 31449853 = 31450026
269 + 31449757 = 31450026
337 + 31449689 = 31450026

Showing the first eight; more decompositions exist.
