Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83420, here are decompositions:
- 3 + 83417 = 83420
- 13 + 83407 = 83420
- 19 + 83401 = 83420
- 31 + 83389 = 83420
- 37 + 83383 = 83420
- 79 + 83341 = 83420
- 109 + 83311 = 83420
- 151 + 83269 = 83420
Showing the first eight; more decompositions exist.
