Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624068, here are decompositions:

67 + 31624001 = 31624068
79 + 31623989 = 31624068
89 + 31623979 = 31624068
97 + 31623971 = 31624068
101 + 31623967 = 31624068
109 + 31623959 = 31624068
137 + 31623931 = 31624068
139 + 31623929 = 31624068

Showing the first eight; more decompositions exist.
