Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294956940, here are decompositions:
- 3 + 4294956937 = 4294956940
- 17 + 4294956923 = 4294956940
- 59 + 4294956881 = 4294956940
- 101 + 4294956839 = 4294956940
- 107 + 4294956833 = 4294956940
- 251 + 4294956689 = 4294956940
- 257 + 4294956683 = 4294956940
- 269 + 4294956671 = 4294956940
Showing the first eight; more decompositions exist.
