Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84478, here are decompositions:
- 11 + 84467 = 84478
- 29 + 84449 = 84478
- 41 + 84437 = 84478
- 47 + 84431 = 84478
- 71 + 84407 = 84478
- 89 + 84389 = 84478
- 101 + 84377 = 84478
- 131 + 84347 = 84478
Showing the first eight; more decompositions exist.
