Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87004, here are decompositions:
- 11 + 86993 = 87004
- 23 + 86981 = 87004
- 53 + 86951 = 87004
- 167 + 86837 = 87004
- 191 + 86813 = 87004
- 233 + 86771 = 87004
- 251 + 86753 = 87004
- 293 + 86711 = 87004
Showing the first eight; more decompositions exist.
