Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972478, here are decompositions:
- 37 + 4294972441 = 4294972478
- 67 + 4294972411 = 4294972478
- 127 + 4294972351 = 4294972478
- 211 + 4294972267 = 4294972478
- 241 + 4294972237 = 4294972478
- 271 + 4294972207 = 4294972478
- 331 + 4294972147 = 4294972478
- 409 + 4294972069 = 4294972478
Showing the first eight; more decompositions exist.
