Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 58720, here are decompositions:
- 41 + 58679 = 58720
- 59 + 58661 = 58720
- 89 + 58631 = 58720
- 107 + 58613 = 58720
- 239 + 58481 = 58720
- 269 + 58451 = 58720
- 281 + 58439 = 58720
- 293 + 58427 = 58720
Showing the first eight; more decompositions exist.
