Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91142, here are decompositions:
- 3 + 91139 = 91142
- 13 + 91129 = 91142
- 43 + 91099 = 91142
- 61 + 91081 = 91142
- 109 + 91033 = 91142
- 211 + 90931 = 91142
- 241 + 90901 = 91142
- 349 + 90793 = 91142
Showing the first eight; more decompositions exist.
