Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86542, here are decompositions:
- 3 + 86539 = 86542
- 11 + 86531 = 86542
- 41 + 86501 = 86542
- 89 + 86453 = 86542
- 101 + 86441 = 86542
- 173 + 86369 = 86542
- 191 + 86351 = 86542
- 251 + 86291 = 86542
Showing the first eight; more decompositions exist.
