Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972178, here are decompositions:
- 31 + 4294972147 = 4294972178
- 61 + 4294972117 = 4294972178
- 109 + 4294972069 = 4294972178
- 127 + 4294972051 = 4294972178
- 139 + 4294972039 = 4294972178
- 241 + 4294971937 = 4294972178
- 337 + 4294971841 = 4294972178
- 349 + 4294971829 = 4294972178
Showing the first eight; more decompositions exist.
