Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72146, here are decompositions:
- 7 + 72139 = 72146
- 37 + 72109 = 72146
- 43 + 72103 = 72146
- 73 + 72073 = 72146
- 103 + 72043 = 72146
- 127 + 72019 = 72146
- 163 + 71983 = 72146
- 199 + 71947 = 72146
Showing the first eight; more decompositions exist.
