Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624074, here are decompositions:

5 + 31624069 = 31624074
61 + 31624013 = 31624074
71 + 31624003 = 31624074
73 + 31624001 = 31624074
103 + 31623971 = 31624074
107 + 31623967 = 31624074
127 + 31623947 = 31624074
173 + 31623901 = 31624074

Showing the first eight; more decompositions exist.
