Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87634, here are decompositions:
- 3 + 87631 = 87634
- 5 + 87629 = 87634
- 11 + 87623 = 87634
- 47 + 87587 = 87634
- 191 + 87443 = 87634
- 227 + 87407 = 87634
- 251 + 87383 = 87634
- 311 + 87323 = 87634
Showing the first eight; more decompositions exist.
