Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83370, here are decompositions:
- 13 + 83357 = 83370
- 29 + 83341 = 83370
- 31 + 83339 = 83370
- 59 + 83311 = 83370
- 71 + 83299 = 83370
- 97 + 83273 = 83370
- 101 + 83269 = 83370
- 103 + 83267 = 83370
Showing the first eight; more decompositions exist.
