Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69642, here are decompositions:
- 19 + 69623 = 69642
- 103 + 69539 = 69642
- 149 + 69493 = 69642
- 151 + 69491 = 69642
- 179 + 69463 = 69642
- 211 + 69431 = 69642
- 239 + 69403 = 69642
- 241 + 69401 = 69642
Showing the first eight; more decompositions exist.
