Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15372, here are decompositions:
- 11 + 15361 = 15372
- 13 + 15359 = 15372
- 23 + 15349 = 15372
- 41 + 15331 = 15372
- 43 + 15329 = 15372
- 53 + 15319 = 15372
- 59 + 15313 = 15372
- 73 + 15299 = 15372
Showing the first eight; more decompositions exist.
