Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30580, here are decompositions:

3 + 30577 = 30580
23 + 30557 = 30580
41 + 30539 = 30580
71 + 30509 = 30580
83 + 30497 = 30580
89 + 30491 = 30580
113 + 30467 = 30580
131 + 30449 = 30580

Showing the first eight; more decompositions exist.
