Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18696, here are decompositions:
- 5 + 18691 = 18696
- 17 + 18679 = 18696
- 59 + 18637 = 18696
- 79 + 18617 = 18696
- 103 + 18593 = 18696
- 109 + 18587 = 18696
- 113 + 18583 = 18696
- 157 + 18539 = 18696
Showing the first eight; more decompositions exist.
