Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30100, here are decompositions:
- 3 + 30097 = 30100
- 11 + 30089 = 30100
- 29 + 30071 = 30100
- 41 + 30059 = 30100
- 53 + 30047 = 30100
- 71 + 30029 = 30100
- 89 + 30011 = 30100
- 173 + 29927 = 30100
Showing the first eight; more decompositions exist.
