Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15764, here are decompositions:
- 3 + 15761 = 15764
- 31 + 15733 = 15764
- 37 + 15727 = 15764
- 97 + 15667 = 15764
- 103 + 15661 = 15764
- 157 + 15607 = 15764
- 163 + 15601 = 15764
- 181 + 15583 = 15764
Showing the first eight; more decompositions exist.
