Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72002, here are decompositions:
- 3 + 71999 = 72002
- 19 + 71983 = 72002
- 31 + 71971 = 72002
- 61 + 71941 = 72002
- 103 + 71899 = 72002
- 181 + 71821 = 72002
- 193 + 71809 = 72002
- 241 + 71761 = 72002
Showing the first eight; more decompositions exist.
