Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978142, here are decompositions:
- 19 + 4294978123 = 4294978142
- 61 + 4294978081 = 4294978142
- 109 + 4294978033 = 4294978142
- 139 + 4294978003 = 4294978142
- 151 + 4294977991 = 4294978142
- 181 + 4294977961 = 4294978142
- 199 + 4294977943 = 4294978142
- 283 + 4294977859 = 4294978142
Showing the first eight; more decompositions exist.
