Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957122, here are decompositions:
- 13 + 4294957109 = 4294957122
- 19 + 4294957103 = 4294957122
- 23 + 4294957099 = 4294957122
- 41 + 4294957081 = 4294957122
- 173 + 4294956949 = 4294957122
- 199 + 4294956923 = 4294957122
- 233 + 4294956889 = 4294957122
- 241 + 4294956881 = 4294957122
Showing the first eight; more decompositions exist.
