Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15226, here are decompositions:
- 53 + 15173 = 15226
- 89 + 15137 = 15226
- 149 + 15077 = 15226
- 173 + 15053 = 15226
- 257 + 14969 = 15226
- 269 + 14957 = 15226
- 347 + 14879 = 15226
- 359 + 14867 = 15226
Showing the first eight; more decompositions exist.
