Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958778, here are decompositions:
- 37 + 4294958741 = 4294958778
- 67 + 4294958711 = 4294958778
- 127 + 4294958651 = 4294958778
- 151 + 4294958627 = 4294958778
- 157 + 4294958621 = 4294958778
- 167 + 4294958611 = 4294958778
- 181 + 4294958597 = 4294958778
- 239 + 4294958539 = 4294958778
Showing the first eight; more decompositions exist.
