Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294970872, here are decompositions:
- 11 + 4294970861 = 4294970872
- 53 + 4294970819 = 4294970872
- 149 + 4294970723 = 4294970872
- 641 + 4294970231 = 4294970872
- 683 + 4294970189 = 4294970872
- 971 + 4294969901 = 4294970872
- 1091 + 4294969781 = 4294970872
- 1229 + 4294969643 = 4294970872
Showing the first eight; more decompositions exist.
