Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15318, here are decompositions:
- 5 + 15313 = 15318
- 11 + 15307 = 15318
- 19 + 15299 = 15318
- 29 + 15289 = 15318
- 31 + 15287 = 15318
- 41 + 15277 = 15318
- 47 + 15271 = 15318
- 59 + 15259 = 15318
Showing the first eight; more decompositions exist.
