Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97990, here are decompositions:

3 + 97987 = 97990
17 + 97973 = 97990
23 + 97967 = 97990
29 + 97961 = 97990
47 + 97943 = 97990
59 + 97931 = 97990
71 + 97919 = 97990
107 + 97883 = 97990

Showing the first eight; more decompositions exist.
