Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87308, here are decompositions:
- 31 + 87277 = 87308
- 97 + 87211 = 87308
- 127 + 87181 = 87308
- 157 + 87151 = 87308
- 271 + 87037 = 87308
- 349 + 86959 = 87308
- 379 + 86929 = 87308
- 439 + 86869 = 87308
Showing the first eight; more decompositions exist.
