Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15102, here are decompositions:
- 11 + 15091 = 15102
- 19 + 15083 = 15102
- 29 + 15073 = 15102
- 41 + 15061 = 15102
- 71 + 15031 = 15102
- 89 + 15013 = 15102
- 151 + 14951 = 15102
- 163 + 14939 = 15102
Showing the first eight; more decompositions exist.
