Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80090, here are decompositions:
- 13 + 80077 = 80090
- 19 + 80071 = 80090
- 103 + 79987 = 80090
- 151 + 79939 = 80090
- 223 + 79867 = 80090
- 229 + 79861 = 80090
- 277 + 79813 = 80090
- 313 + 79777 = 80090
Showing the first eight; more decompositions exist.
