Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958240, here are decompositions:
- 3 + 4294958237 = 4294958240
- 43 + 4294958197 = 4294958240
- 109 + 4294958131 = 4294958240
- 163 + 4294958077 = 4294958240
- 229 + 4294958011 = 4294958240
- 283 + 4294957957 = 4294958240
- 337 + 4294957903 = 4294958240
- 379 + 4294957861 = 4294958240
Showing the first eight; more decompositions exist.
