Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 113580, here are decompositions:

13 + 113567 = 113580
23 + 113557 = 113580
41 + 113539 = 113580
43 + 113537 = 113580
67 + 113513 = 113580
79 + 113501 = 113580
83 + 113497 = 113580
113 + 113467 = 113580

Showing the first eight; more decompositions exist.
