Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42472, here are decompositions:
- 5 + 42467 = 42472
- 11 + 42461 = 42472
- 29 + 42443 = 42472
- 113 + 42359 = 42472
- 149 + 42323 = 42472
- 173 + 42299 = 42472
- 179 + 42293 = 42472
- 191 + 42281 = 42472
Showing the first eight; more decompositions exist.
