Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18764, here are decompositions:
- 7 + 18757 = 18764
- 73 + 18691 = 18764
- 103 + 18661 = 18764
- 127 + 18637 = 18764
- 181 + 18583 = 18764
- 211 + 18553 = 18764
- 223 + 18541 = 18764
- 241 + 18523 = 18764
Showing the first eight; more decompositions exist.
