Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85490, here are decompositions:

3 + 85487 = 85490
37 + 85453 = 85490
43 + 85447 = 85490
61 + 85429 = 85490
79 + 85411 = 85490
109 + 85381 = 85490
127 + 85363 = 85490
157 + 85333 = 85490

Showing the first eight; more decompositions exist.
