Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91002, here are decompositions:
- 5 + 90997 = 91002
- 13 + 90989 = 91002
- 31 + 90971 = 91002
- 71 + 90931 = 91002
- 101 + 90901 = 91002
- 139 + 90863 = 91002
- 179 + 90823 = 91002
- 181 + 90821 = 91002
Showing the first eight; more decompositions exist.
