Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72036, here are decompositions:

5 + 72031 = 72036
17 + 72019 = 72036
37 + 71999 = 72036
43 + 71993 = 72036
53 + 71983 = 72036
73 + 71963 = 72036
89 + 71947 = 72036
103 + 71933 = 72036

Showing the first eight; more decompositions exist.
