Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972888, here are decompositions:
- 29 + 4294972859 = 4294972888
- 137 + 4294972751 = 4294972888
- 467 + 4294972421 = 4294972888
- 809 + 4294972079 = 4294972888
- 827 + 4294972061 = 4294972888
- 839 + 4294972049 = 4294972888
- 1499 + 4294971389 = 4294972888
- 1511 + 4294971377 = 4294972888
Showing the first eight; more decompositions exist.
