Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580, here are decompositions:
- 3 + 577 = 580
- 11 + 569 = 580
- 17 + 563 = 580
- 23 + 557 = 580
- 59 + 521 = 580
- 71 + 509 = 580
- 89 + 491 = 580
- 101 + 479 = 580
Showing the first eight; more decompositions exist.
