Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90642, here are decompositions:

11 + 90631 = 90642
23 + 90619 = 90642
43 + 90599 = 90642
59 + 90583 = 90642
109 + 90533 = 90642
113 + 90529 = 90642
131 + 90511 = 90642
173 + 90469 = 90642

Showing the first eight; more decompositions exist.
