Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87250, here are decompositions:
- 29 + 87221 = 87250
- 71 + 87179 = 87250
- 101 + 87149 = 87250
- 131 + 87119 = 87250
- 167 + 87083 = 87250
- 179 + 87071 = 87250
- 239 + 87011 = 87250
- 257 + 86993 = 87250
Showing the first eight; more decompositions exist.
