Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18360, here are decompositions:
- 7 + 18353 = 18360
- 19 + 18341 = 18360
- 31 + 18329 = 18360
- 47 + 18313 = 18360
- 53 + 18307 = 18360
- 59 + 18301 = 18360
- 71 + 18289 = 18360
- 73 + 18287 = 18360
Showing the first eight; more decompositions exist.
