Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624126, here are decompositions:

113 + 31624013 = 31624126
137 + 31623989 = 31624126
167 + 31623959 = 31624126
173 + 31623953 = 31624126
179 + 31623947 = 31624126
197 + 31623929 = 31624126
239 + 31623887 = 31624126
269 + 31623857 = 31624126

Showing the first eight; more decompositions exist.
