Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87862, here are decompositions:
- 29 + 87833 = 87862
- 59 + 87803 = 87862
- 179 + 87683 = 87862
- 191 + 87671 = 87862
- 233 + 87629 = 87862
- 239 + 87623 = 87862
- 353 + 87509 = 87862
- 389 + 87473 = 87862
Showing the first eight; more decompositions exist.
