Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146580, here are decompositions:

17 + 146563 = 146580
37 + 146543 = 146580
41 + 146539 = 146580
53 + 146527 = 146580
59 + 146521 = 146580
61 + 146519 = 146580
67 + 146513 = 146580
103 + 146477 = 146580

Showing the first eight; more decompositions exist.
