Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72140, here are decompositions:

31 + 72109 = 72140
37 + 72103 = 72140
67 + 72073 = 72140
97 + 72043 = 72140
109 + 72031 = 72140
157 + 71983 = 72140
193 + 71947 = 72140
199 + 71941 = 72140

Showing the first eight; more decompositions exist.
