Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624122, here are decompositions:

53 + 31624069 = 31624122
109 + 31624013 = 31624122
139 + 31623983 = 31624122
151 + 31623971 = 31624122
163 + 31623959 = 31624122
191 + 31623931 = 31624122
193 + 31623929 = 31624122
401 + 31623721 = 31624122

Showing the first eight; more decompositions exist.
