Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15232, here are decompositions:
- 5 + 15227 = 15232
- 59 + 15173 = 15232
- 71 + 15161 = 15232
- 83 + 15149 = 15232
- 101 + 15131 = 15232
- 131 + 15101 = 15232
- 149 + 15083 = 15232
- 179 + 15053 = 15232
Showing the first eight; more decompositions exist.
