Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84090, here are decompositions:
- 23 + 84067 = 84090
- 29 + 84061 = 84090
- 31 + 84059 = 84090
- 37 + 84053 = 84090
- 43 + 84047 = 84090
- 73 + 84017 = 84090
- 79 + 84011 = 84090
- 103 + 83987 = 84090
Showing the first eight; more decompositions exist.
