Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72078, here are decompositions:

5 + 72073 = 72078
31 + 72047 = 72078
47 + 72031 = 72078
59 + 72019 = 72078
79 + 71999 = 72078
107 + 71971 = 72078
131 + 71947 = 72078
137 + 71941 = 72078

Showing the first eight; more decompositions exist.
