Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87238, here are decompositions:
- 17 + 87221 = 87238
- 59 + 87179 = 87238
- 89 + 87149 = 87238
- 131 + 87107 = 87238
- 167 + 87071 = 87238
- 197 + 87041 = 87238
- 227 + 87011 = 87238
- 257 + 86981 = 87238
Showing the first eight; more decompositions exist.
