Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 58128, here are decompositions:
- 17 + 58111 = 58128
- 19 + 58109 = 58128
- 29 + 58099 = 58128
- 61 + 58067 = 58128
- 67 + 58061 = 58128
- 71 + 58057 = 58128
- 79 + 58049 = 58128
- 97 + 58031 = 58128
Showing the first eight; more decompositions exist.
