Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15148, here are decompositions:
- 11 + 15137 = 15148
- 17 + 15131 = 15148
- 41 + 15107 = 15148
- 47 + 15101 = 15148
- 71 + 15077 = 15148
- 131 + 15017 = 15148
- 179 + 14969 = 15148
- 191 + 14957 = 15148
Showing the first eight; more decompositions exist.
