Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84778, here are decompositions:
- 17 + 84761 = 84778
- 41 + 84737 = 84778
- 47 + 84731 = 84778
- 59 + 84719 = 84778
- 149 + 84629 = 84778
- 227 + 84551 = 84778
- 257 + 84521 = 84778
- 269 + 84509 = 84778
Showing the first eight; more decompositions exist.
