Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80312, here are decompositions:
- 3 + 80309 = 80312
- 61 + 80251 = 80312
- 73 + 80239 = 80312
- 79 + 80233 = 80312
- 103 + 80209 = 80312
- 139 + 80173 = 80312
- 163 + 80149 = 80312
- 241 + 80071 = 80312
Showing the first eight; more decompositions exist.
