Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294970642, here are decompositions:
- 73 + 4294970569 = 4294970642
- 139 + 4294970503 = 4294970642
- 199 + 4294970443 = 4294970642
- 643 + 4294969999 = 4294970642
- 691 + 4294969951 = 4294970642
- 811 + 4294969831 = 4294970642
- 829 + 4294969813 = 4294970642
- 883 + 4294969759 = 4294970642
Showing the first eight; more decompositions exist.
