Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624038, here are decompositions:

37 + 31624001 = 31624038
59 + 31623979 = 31624038
67 + 31623971 = 31624038
71 + 31623967 = 31624038
79 + 31623959 = 31624038
107 + 31623931 = 31624038
109 + 31623929 = 31624038
137 + 31623901 = 31624038

Showing the first eight; more decompositions exist.
