Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87764, here are decompositions:
- 13 + 87751 = 87764
- 43 + 87721 = 87764
- 67 + 87697 = 87764
- 73 + 87691 = 87764
- 151 + 87613 = 87764
- 181 + 87583 = 87764
- 211 + 87553 = 87764
- 223 + 87541 = 87764
Showing the first eight; more decompositions exist.
