Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18430, here are decompositions:
- 3 + 18427 = 18430
- 17 + 18413 = 18430
- 29 + 18401 = 18430
- 59 + 18371 = 18430
- 89 + 18341 = 18430
- 101 + 18329 = 18430
- 173 + 18257 = 18430
- 179 + 18251 = 18430
Showing the first eight; more decompositions exist.
