Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30150, here are decompositions:
- 11 + 30139 = 30150
- 13 + 30137 = 30150
- 17 + 30133 = 30150
- 31 + 30119 = 30150
- 37 + 30113 = 30150
- 41 + 30109 = 30150
- 47 + 30103 = 30150
- 53 + 30097 = 30150
Showing the first eight; more decompositions exist.
