Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87000, here are decompositions:
- 7 + 86993 = 87000
- 19 + 86981 = 87000
- 31 + 86969 = 87000
- 41 + 86959 = 87000
- 61 + 86939 = 87000
- 71 + 86929 = 87000
- 73 + 86927 = 87000
- 131 + 86869 = 87000
Showing the first eight; more decompositions exist.
