Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78684, here are decompositions:
- 31 + 78653 = 78684
- 41 + 78643 = 78684
- 61 + 78623 = 78684
- 101 + 78583 = 78684
- 107 + 78577 = 78684
- 113 + 78571 = 78684
- 131 + 78553 = 78684
- 167 + 78517 = 78684
Showing the first eight; more decompositions exist.
