Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463126, here are decompositions:

3 + 31463123 = 31463126
43 + 31463083 = 31463126
103 + 31463023 = 31463126
157 + 31462969 = 31463126
193 + 31462933 = 31463126
229 + 31462897 = 31463126
367 + 31462759 = 31463126
379 + 31462747 = 31463126

Showing the first eight; more decompositions exist.
