Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126198, here are decompositions:
- 47 + 126151 = 126198
- 67 + 126131 = 126198
- 71 + 126127 = 126198
- 101 + 126097 = 126198
- 131 + 126067 = 126198
- 151 + 126047 = 126198
- 157 + 126041 = 126198
- 167 + 126031 = 126198
Showing the first eight; more decompositions exist.
