Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961778, here are decompositions:
- 11 + 4294961767 = 4294961778
- 31 + 4294961747 = 4294961778
- 71 + 4294961707 = 4294961778
- 181 + 4294961597 = 4294961778
- 199 + 4294961579 = 4294961778
- 251 + 4294961527 = 4294961778
- 257 + 4294961521 = 4294961778
- 271 + 4294961507 = 4294961778
Showing the first eight; more decompositions exist.
