Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30002, here are decompositions:
- 13 + 29989 = 30002
- 19 + 29983 = 30002
- 43 + 29959 = 30002
- 139 + 29863 = 30002
- 151 + 29851 = 30002
- 199 + 29803 = 30002
- 241 + 29761 = 30002
- 331 + 29671 = 30002
Showing the first eight; more decompositions exist.
