Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84580, here are decompositions:

29 + 84551 = 84580
47 + 84533 = 84580
59 + 84521 = 84580
71 + 84509 = 84580
113 + 84467 = 84580
131 + 84449 = 84580
137 + 84443 = 84580
149 + 84431 = 84580

Showing the first eight; more decompositions exist.
