Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126148, here are decompositions:
- 5 + 126143 = 126148
- 17 + 126131 = 126148
- 41 + 126107 = 126148
- 101 + 126047 = 126148
- 107 + 126041 = 126148
- 137 + 126011 = 126148
- 227 + 125921 = 126148
- 251 + 125897 = 126148
Showing the first eight; more decompositions exist.
