Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 58212, here are decompositions:
- 5 + 58207 = 58212
- 13 + 58199 = 58212
- 19 + 58193 = 58212
- 23 + 58189 = 58212
- 41 + 58171 = 58212
- 43 + 58169 = 58212
- 59 + 58153 = 58212
- 61 + 58151 = 58212
Showing the first eight; more decompositions exist.
