Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187342, here are decompositions:
- 3 + 187339 = 187342
- 5 + 187337 = 187342
- 131 + 187211 = 187342
- 149 + 187193 = 187342
- 179 + 187163 = 187342
- 251 + 187091 = 187342
- 269 + 187073 = 187342
- 293 + 187049 = 187342
Showing the first eight; more decompositions exist.
