Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87338, here are decompositions:
- 61 + 87277 = 87338
- 127 + 87211 = 87338
- 151 + 87187 = 87338
- 157 + 87181 = 87338
- 379 + 86959 = 87338
- 409 + 86929 = 87338
- 487 + 86851 = 87338
- 571 + 86767 = 87338
Showing the first eight; more decompositions exist.
