Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18464, here are decompositions:
- 3 + 18461 = 18464
- 7 + 18457 = 18464
- 13 + 18451 = 18464
- 31 + 18433 = 18464
- 37 + 18427 = 18464
- 67 + 18397 = 18464
- 97 + 18367 = 18464
- 151 + 18313 = 18464
Showing the first eight; more decompositions exist.
