Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187352, here are decompositions:
- 3 + 187349 = 187352
- 13 + 187339 = 187352
- 79 + 187273 = 187352
- 163 + 187189 = 187352
- 181 + 187171 = 187352
- 211 + 187141 = 187352
- 223 + 187129 = 187352
- 229 + 187123 = 187352
Showing the first eight; more decompositions exist.
