Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294963990, here are decompositions:
- 3 + 4294963987 = 4294963990
- 47 + 4294963943 = 4294963990
- 89 + 4294963901 = 4294963990
- 137 + 4294963853 = 4294963990
- 347 + 4294963643 = 4294963990
- 353 + 4294963637 = 4294963990
- 419 + 4294963571 = 4294963990
- 467 + 4294963523 = 4294963990
Showing the first eight; more decompositions exist.
