Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84738, here are decompositions:
- 7 + 84731 = 84738
- 19 + 84719 = 84738
- 37 + 84701 = 84738
- 41 + 84697 = 84738
- 47 + 84691 = 84738
- 79 + 84659 = 84738
- 89 + 84649 = 84738
- 107 + 84631 = 84738
Showing the first eight; more decompositions exist.
