Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958144, here are decompositions:
- 13 + 4294958131 = 4294958144
- 67 + 4294958077 = 4294958144
- 73 + 4294958071 = 4294958144
- 241 + 4294957903 = 4294958144
- 283 + 4294957861 = 4294958144
- 877 + 4294957267 = 4294958144
- 937 + 4294957207 = 4294958144
- 1021 + 4294957123 = 4294958144
Showing the first eight; more decompositions exist.
