Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978138, here are decompositions:
- 5 + 4294978133 = 4294978138
- 47 + 4294978091 = 4294978138
- 71 + 4294978067 = 4294978138
- 149 + 4294977989 = 4294978138
- 239 + 4294977899 = 4294978138
- 257 + 4294977881 = 4294978138
- 467 + 4294977671 = 4294978138
- 719 + 4294977419 = 4294978138
Showing the first eight; more decompositions exist.
