Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73666, here are decompositions:
- 23 + 73643 = 73666
- 29 + 73637 = 73666
- 53 + 73613 = 73666
- 59 + 73607 = 73666
- 83 + 73583 = 73666
- 113 + 73553 = 73666
- 137 + 73529 = 73666
- 149 + 73517 = 73666
Showing the first eight; more decompositions exist.
