Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87244, here are decompositions:
- 23 + 87221 = 87244
- 137 + 87107 = 87244
- 173 + 87071 = 87244
- 233 + 87011 = 87244
- 251 + 86993 = 87244
- 263 + 86981 = 87244
- 293 + 86951 = 87244
- 317 + 86927 = 87244
Showing the first eight; more decompositions exist.
