Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42372, here are decompositions:
- 13 + 42359 = 42372
- 23 + 42349 = 42372
- 41 + 42331 = 42372
- 73 + 42299 = 42372
- 79 + 42293 = 42372
- 89 + 42283 = 42372
- 149 + 42223 = 42372
- 151 + 42221 = 42372
Showing the first eight; more decompositions exist.
