Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 60990, here are decompositions:

29 + 60961 = 60990
37 + 60953 = 60990
47 + 60943 = 60990
53 + 60937 = 60990
67 + 60923 = 60990
71 + 60919 = 60990
73 + 60917 = 60990
89 + 60901 = 60990

Showing the first eight; more decompositions exist.
