Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4258, here are decompositions:
- 5 + 4253 = 4258
- 17 + 4241 = 4258
- 29 + 4229 = 4258
- 41 + 4217 = 4258
- 47 + 4211 = 4258
- 101 + 4157 = 4258
- 131 + 4127 = 4258
- 167 + 4091 = 4258
Showing the first eight; more decompositions exist.
