Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15382, here are decompositions:
- 5 + 15377 = 15382
- 23 + 15359 = 15382
- 53 + 15329 = 15382
- 83 + 15299 = 15382
- 113 + 15269 = 15382
- 149 + 15233 = 15382
- 233 + 15149 = 15382
- 251 + 15131 = 15382
Showing the first eight; more decompositions exist.
