Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294956942, here are decompositions:
- 5 + 4294956937 = 4294956942
- 19 + 4294956923 = 4294956942
- 41 + 4294956901 = 4294956942
- 53 + 4294956889 = 4294956942
- 61 + 4294956881 = 4294956942
- 79 + 4294956863 = 4294956942
- 103 + 4294956839 = 4294956942
- 109 + 4294956833 = 4294956942
Showing the first eight; more decompositions exist.
