Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84078, here are decompositions:
- 11 + 84067 = 84078
- 17 + 84061 = 84078
- 19 + 84059 = 84078
- 31 + 84047 = 84078
- 61 + 84017 = 84078
- 67 + 84011 = 84078
- 109 + 83969 = 84078
- 139 + 83939 = 84078
Showing the first eight; more decompositions exist.
