Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42802, here are decompositions:
- 5 + 42797 = 42802
- 29 + 42773 = 42802
- 59 + 42743 = 42802
- 83 + 42719 = 42802
- 101 + 42701 = 42802
- 113 + 42689 = 42802
- 191 + 42611 = 42802
- 233 + 42569 = 42802
Showing the first eight; more decompositions exist.
