Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624066, here are decompositions:

53 + 31624013 = 31624066
83 + 31623983 = 31624066
107 + 31623959 = 31624066
113 + 31623953 = 31624066
137 + 31623929 = 31624066
179 + 31623887 = 31624066
269 + 31623797 = 31624066
359 + 31623707 = 31624066

Showing the first eight; more decompositions exist.
