Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83400, here are decompositions:
- 11 + 83389 = 83400
- 17 + 83383 = 83400
- 43 + 83357 = 83400
- 59 + 83341 = 83400
- 61 + 83339 = 83400
- 89 + 83311 = 83400
- 101 + 83299 = 83400
- 127 + 83273 = 83400
Showing the first eight; more decompositions exist.
