Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40580, here are decompositions:

3 + 40577 = 40580
37 + 40543 = 40580
61 + 40519 = 40580
73 + 40507 = 40580
97 + 40483 = 40580
109 + 40471 = 40580
151 + 40429 = 40580
157 + 40423 = 40580

Showing the first eight; more decompositions exist.
