Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957866, here are decompositions:
- 5 + 4294957861 = 4294957866
- 7 + 4294957859 = 4294957866
- 13 + 4294957853 = 4294957866
- 113 + 4294957753 = 4294957866
- 137 + 4294957729 = 4294957866
- 149 + 4294957717 = 4294957866
- 163 + 4294957703 = 4294957866
- 167 + 4294957699 = 4294957866
Showing the first eight; more decompositions exist.
