Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961918, here are decompositions:
- 109 + 4294961809 = 4294961918
- 127 + 4294961791 = 4294961918
- 151 + 4294961767 = 4294961918
- 211 + 4294961707 = 4294961918
- 397 + 4294961521 = 4294961918
- 601 + 4294961317 = 4294961918
- 631 + 4294961287 = 4294961918
- 739 + 4294961179 = 4294961918
Showing the first eight; more decompositions exist.
