Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87468, here are decompositions:
- 41 + 87427 = 87468
- 47 + 87421 = 87468
- 61 + 87407 = 87468
- 109 + 87359 = 87468
- 131 + 87337 = 87468
- 151 + 87317 = 87468
- 191 + 87277 = 87468
- 211 + 87257 = 87468
Showing the first eight; more decompositions exist.
