Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961216, here are decompositions:
- 19 + 4294961197 = 4294961216
- 37 + 4294961179 = 4294961216
- 79 + 4294961137 = 4294961216
- 97 + 4294961119 = 4294961216
- 193 + 4294961023 = 4294961216
- 379 + 4294960837 = 4294961216
- 433 + 4294960783 = 4294961216
- 457 + 4294960759 = 4294961216
Showing the first eight; more decompositions exist.
