Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978172, here are decompositions:
- 3 + 4294978169 = 4294978172
- 139 + 4294978033 = 4294978172
- 151 + 4294978021 = 4294978172
- 181 + 4294977991 = 4294978172
- 211 + 4294977961 = 4294978172
- 229 + 4294977943 = 4294978172
- 313 + 4294977859 = 4294978172
- 349 + 4294977823 = 4294978172
Showing the first eight; more decompositions exist.
