Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16430, here are decompositions:
- 3 + 16427 = 16430
- 13 + 16417 = 16430
- 19 + 16411 = 16430
- 61 + 16369 = 16430
- 67 + 16363 = 16430
- 97 + 16333 = 16430
- 157 + 16273 = 16430
- 163 + 16267 = 16430
Showing the first eight; more decompositions exist.
