Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30242, here are decompositions:
- 19 + 30223 = 30242
- 31 + 30211 = 30242
- 61 + 30181 = 30242
- 73 + 30169 = 30242
- 103 + 30139 = 30242
- 109 + 30133 = 30242
- 139 + 30103 = 30242
- 151 + 30091 = 30242
Showing the first eight; more decompositions exist.
