Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111580, here are decompositions:

3 + 111577 = 111580
41 + 111539 = 111580
47 + 111533 = 111580
59 + 111521 = 111580
71 + 111509 = 111580
83 + 111497 = 111580
89 + 111491 = 111580
113 + 111467 = 111580

Showing the first eight; more decompositions exist.
