Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 802, here are decompositions:
- 5 + 797 = 802
- 29 + 773 = 802
- 41 + 761 = 802
- 59 + 743 = 802
- 83 + 719 = 802
- 101 + 701 = 802
- 149 + 653 = 802
- 233 + 569 = 802
Showing the first eight; more decompositions exist.
