Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456126, here are decompositions:

3 + 31456123 = 31456126
5 + 31456121 = 31456126
47 + 31456079 = 31456126
59 + 31456067 = 31456126
113 + 31456013 = 31456126
167 + 31455959 = 31456126
179 + 31455947 = 31456126
197 + 31455929 = 31456126

Showing the first eight; more decompositions exist.
