Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83390, here are decompositions:
- 7 + 83383 = 83390
- 79 + 83311 = 83390
- 157 + 83233 = 83390
- 163 + 83227 = 83390
- 313 + 83077 = 83390
- 331 + 83059 = 83390
- 367 + 83023 = 83390
- 409 + 82981 = 83390
Showing the first eight; more decompositions exist.
