Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72990, here are decompositions:

13 + 72977 = 72990
17 + 72973 = 72990
31 + 72959 = 72990
37 + 72953 = 72990
41 + 72949 = 72990
53 + 72937 = 72990
59 + 72931 = 72990
67 + 72923 = 72990

Showing the first eight; more decompositions exist.
