Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84784, here are decompositions:
- 23 + 84761 = 84784
- 47 + 84737 = 84784
- 53 + 84731 = 84784
- 71 + 84713 = 84784
- 83 + 84701 = 84784
- 131 + 84653 = 84784
- 233 + 84551 = 84784
- 251 + 84533 = 84784
Showing the first eight; more decompositions exist.
