Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87694, here are decompositions:
- 3 + 87691 = 87694
- 11 + 87683 = 87694
- 23 + 87671 = 87694
- 53 + 87641 = 87694
- 71 + 87623 = 87694
- 107 + 87587 = 87694
- 137 + 87557 = 87694
- 251 + 87443 = 87694
Showing the first eight; more decompositions exist.
