Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624162, here are decompositions:

149 + 31624013 = 31624162
173 + 31623989 = 31624162
179 + 31623983 = 31624162
191 + 31623971 = 31624162
233 + 31623929 = 31624162
431 + 31623731 = 31624162
461 + 31623701 = 31624162
491 + 31623671 = 31624162

Showing the first eight; more decompositions exist.
