Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15230, here are decompositions:
- 3 + 15227 = 15230
- 13 + 15217 = 15230
- 31 + 15199 = 15230
- 37 + 15193 = 15230
- 43 + 15187 = 15230
- 109 + 15121 = 15230
- 139 + 15091 = 15230
- 157 + 15073 = 15230
Showing the first eight; more decompositions exist.
