Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84880, here are decompositions:
- 11 + 84869 = 84880
- 23 + 84857 = 84880
- 53 + 84827 = 84880
- 71 + 84809 = 84880
- 149 + 84731 = 84880
- 167 + 84713 = 84880
- 179 + 84701 = 84880
- 227 + 84653 = 84880
Showing the first eight; more decompositions exist.
