Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80390, here are decompositions:
- 3 + 80387 = 80390
- 43 + 80347 = 80390
- 61 + 80329 = 80390
- 73 + 80317 = 80390
- 103 + 80287 = 80390
- 127 + 80263 = 80390
- 139 + 80251 = 80390
- 151 + 80239 = 80390
Showing the first eight; more decompositions exist.
