Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91642, here are decompositions:

3 + 91639 = 91642
11 + 91631 = 91642
59 + 91583 = 91642
71 + 91571 = 91642
101 + 91541 = 91642
113 + 91529 = 91642
149 + 91493 = 91642
179 + 91463 = 91642

Showing the first eight; more decompositions exist.
