Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972578, here are decompositions:
- 11 + 4294972567 = 4294972578
- 19 + 4294972559 = 4294972578
- 97 + 4294972481 = 4294972578
- 137 + 4294972441 = 4294972578
- 157 + 4294972421 = 4294972578
- 167 + 4294972411 = 4294972578
- 227 + 4294972351 = 4294972578
- 241 + 4294972337 = 4294972578
Showing the first eight; more decompositions exist.
