Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90790, here are decompositions:

3 + 90787 = 90790
41 + 90749 = 90790
59 + 90731 = 90790
113 + 90677 = 90790
131 + 90659 = 90790
149 + 90641 = 90790
173 + 90617 = 90790
191 + 90599 = 90790

Showing the first eight; more decompositions exist.
