Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13618, here are decompositions:
- 5 + 13613 = 13618
- 41 + 13577 = 13618
- 131 + 13487 = 13618
- 149 + 13469 = 13618
- 167 + 13451 = 13618
- 197 + 13421 = 13618
- 251 + 13367 = 13618
- 281 + 13337 = 13618
Showing the first eight; more decompositions exist.
