Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90668, here are decompositions:

37 + 90631 = 90668
139 + 90529 = 90668
157 + 90511 = 90668
199 + 90469 = 90668
229 + 90439 = 90668
271 + 90397 = 90668
379 + 90289 = 90668
397 + 90271 = 90668

Showing the first eight; more decompositions exist.
