Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974920, here are decompositions:
- 3 + 4294974917 = 4294974920
- 7 + 4294974913 = 4294974920
- 109 + 4294974811 = 4294974920
- 127 + 4294974793 = 4294974920
- 151 + 4294974769 = 4294974920
- 337 + 4294974583 = 4294974920
- 463 + 4294974457 = 4294974920
- 787 + 4294974133 = 4294974920
Showing the first eight; more decompositions exist.
