Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10002, here are decompositions:
- 29 + 9973 = 10002
- 53 + 9949 = 10002
- 61 + 9941 = 10002
- 71 + 9931 = 10002
- 73 + 9929 = 10002
- 79 + 9923 = 10002
- 101 + 9901 = 10002
- 131 + 9871 = 10002
Showing the first eight; more decompositions exist.
