Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42430, here are decompositions:
- 23 + 42407 = 42430
- 71 + 42359 = 42430
- 107 + 42323 = 42430
- 131 + 42299 = 42430
- 137 + 42293 = 42430
- 149 + 42281 = 42430
- 173 + 42257 = 42430
- 191 + 42239 = 42430
Showing the first eight; more decompositions exist.
