Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2372, here are decompositions:
- 31 + 2341 = 2372
- 61 + 2311 = 2372
- 79 + 2293 = 2372
- 103 + 2269 = 2372
- 151 + 2221 = 2372
- 193 + 2179 = 2372
- 211 + 2161 = 2372
- 229 + 2143 = 2372
Showing the first eight; more decompositions exist.
