Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72074, here are decompositions:

31 + 72043 = 72074
43 + 72031 = 72074
103 + 71971 = 72074
127 + 71947 = 72074
157 + 71917 = 72074
193 + 71881 = 72074
313 + 71761 = 72074
367 + 71707 = 72074

Showing the first eight; more decompositions exist.
