Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90980, here are decompositions:

3 + 90977 = 90980
73 + 90907 = 90980
79 + 90901 = 90980
139 + 90841 = 90980
157 + 90823 = 90980
193 + 90787 = 90980
271 + 90709 = 90980
277 + 90703 = 90980

Showing the first eight; more decompositions exist.
