Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66590, here are decompositions:

3 + 66587 = 66590
19 + 66571 = 66590
37 + 66553 = 66590
61 + 66529 = 66590
67 + 66523 = 66590
127 + 66463 = 66590
229 + 66361 = 66590
421 + 66169 = 66590

Showing the first eight; more decompositions exist.
