Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67812, here are decompositions:
- 5 + 67807 = 67812
- 11 + 67801 = 67812
- 23 + 67789 = 67812
- 29 + 67783 = 67812
- 53 + 67759 = 67812
- 61 + 67751 = 67812
- 71 + 67741 = 67812
- 79 + 67733 = 67812
Showing the first eight; more decompositions exist.
