Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126976, here are decompositions:
- 53 + 126923 = 126976
- 137 + 126839 = 126976
- 149 + 126827 = 126976
- 233 + 126743 = 126976
- 257 + 126719 = 126976
- 263 + 126713 = 126976
- 293 + 126683 = 126976
- 503 + 126473 = 126976
Showing the first eight; more decompositions exist.
