Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30102, here are decompositions:
- 5 + 30097 = 30102
- 11 + 30091 = 30102
- 13 + 30089 = 30102
- 31 + 30071 = 30102
- 43 + 30059 = 30102
- 73 + 30029 = 30102
- 89 + 30013 = 30102
- 113 + 29989 = 30102
Showing the first eight; more decompositions exist.
