Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40430, here are decompositions:
- 3 + 40427 = 40430
- 7 + 40423 = 40430
- 43 + 40387 = 40430
- 73 + 40357 = 40430
- 79 + 40351 = 40430
- 193 + 40237 = 40430
- 199 + 40231 = 40430
- 241 + 40189 = 40430
Showing the first eight; more decompositions exist.
