Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958878, here are decompositions:
- 17 + 4294958861 = 4294958878
- 101 + 4294958777 = 4294958878
- 137 + 4294958741 = 4294958878
- 149 + 4294958729 = 4294958878
- 167 + 4294958711 = 4294958878
- 227 + 4294958651 = 4294958878
- 251 + 4294958627 = 4294958878
- 257 + 4294958621 = 4294958878
Showing the first eight; more decompositions exist.
