Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80290, here are decompositions:
- 3 + 80287 = 80290
- 11 + 80279 = 80290
- 17 + 80273 = 80290
- 59 + 80231 = 80290
- 83 + 80207 = 80290
- 113 + 80177 = 80290
- 137 + 80153 = 80290
- 149 + 80141 = 80290
Showing the first eight; more decompositions exist.
