Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957942, here are decompositions:
- 3 + 4294957939 = 4294957942
- 83 + 4294957859 = 4294957942
- 89 + 4294957853 = 4294957942
- 101 + 4294957841 = 4294957942
- 239 + 4294957703 = 4294957942
- 263 + 4294957679 = 4294957942
- 389 + 4294957553 = 4294957942
- 419 + 4294957523 = 4294957942
Showing the first eight; more decompositions exist.
