Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87488, here are decompositions:
- 7 + 87481 = 87488
- 61 + 87427 = 87488
- 67 + 87421 = 87488
- 151 + 87337 = 87488
- 211 + 87277 = 87488
- 277 + 87211 = 87488
- 307 + 87181 = 87488
- 337 + 87151 = 87488
Showing the first eight; more decompositions exist.
