Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15156, here are decompositions:
- 7 + 15149 = 15156
- 17 + 15139 = 15156
- 19 + 15137 = 15156
- 73 + 15083 = 15156
- 79 + 15077 = 15156
- 83 + 15073 = 15156
- 103 + 15053 = 15156
- 139 + 15017 = 15156
Showing the first eight; more decompositions exist.
