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.
