Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80258, here are decompositions:
- 7 + 80251 = 80258
- 19 + 80239 = 80258
- 37 + 80221 = 80258
- 67 + 80191 = 80258
- 109 + 80149 = 80258
- 151 + 80107 = 80258
- 181 + 80077 = 80258
- 271 + 79987 = 80258
Showing the first eight; more decompositions exist.
