Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957788, here are decompositions:
- 7 + 4294957781 = 4294957788
- 59 + 4294957729 = 4294957788
- 71 + 4294957717 = 4294957788
- 89 + 4294957699 = 4294957788
- 109 + 4294957679 = 4294957788
- 179 + 4294957609 = 4294957788
- 349 + 4294957439 = 4294957788
- 389 + 4294957399 = 4294957788
Showing the first eight; more decompositions exist.
