Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67990, here are decompositions:

3 + 67987 = 67990
11 + 67979 = 67990
23 + 67967 = 67990
29 + 67961 = 67990
47 + 67943 = 67990
59 + 67931 = 67990
89 + 67901 = 67990
107 + 67883 = 67990

Showing the first eight; more decompositions exist.
