Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 150, here are decompositions:
- 11 + 139 = 150
- 13 + 137 = 150
- 19 + 131 = 150
- 23 + 127 = 150
- 37 + 113 = 150
- 41 + 109 = 150
- 43 + 107 = 150
- 47 + 103 = 150
Showing the first eight; more decompositions exist.
