Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972778, here are decompositions:
- 199 + 4294972579 = 4294972778
- 211 + 4294972567 = 4294972778
- 337 + 4294972441 = 4294972778
- 367 + 4294972411 = 4294972778
- 487 + 4294972291 = 4294972778
- 541 + 4294972237 = 4294972778
- 571 + 4294972207 = 4294972778
- 631 + 4294972147 = 4294972778
Showing the first eight; more decompositions exist.
