Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12238, here are decompositions:
- 11 + 12227 = 12238
- 41 + 12197 = 12238
- 89 + 12149 = 12238
- 131 + 12107 = 12238
- 137 + 12101 = 12238
- 167 + 12071 = 12238
- 197 + 12041 = 12238
- 227 + 12011 = 12238
Showing the first eight; more decompositions exist.
