Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624084, here are decompositions:

71 + 31624013 = 31624084
83 + 31624001 = 31624084
101 + 31623983 = 31624084
113 + 31623971 = 31624084
131 + 31623953 = 31624084
137 + 31623947 = 31624084
197 + 31623887 = 31624084
227 + 31623857 = 31624084

Showing the first eight; more decompositions exist.
