Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87386, here are decompositions:
- 3 + 87383 = 87386
- 73 + 87313 = 87386
- 109 + 87277 = 87386
- 163 + 87223 = 87386
- 199 + 87187 = 87386
- 283 + 87103 = 87386
- 337 + 87049 = 87386
- 349 + 87037 = 87386
Showing the first eight; more decompositions exist.
