Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126396, here are decompositions:
- 37 + 126359 = 126396
- 47 + 126349 = 126396
- 59 + 126337 = 126396
- 73 + 126323 = 126396
- 79 + 126317 = 126396
- 89 + 126307 = 126396
- 139 + 126257 = 126396
- 163 + 126233 = 126396
Showing the first eight; more decompositions exist.
