Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975772, here are decompositions:
- 19 + 4294975753 = 4294975772
- 211 + 4294975561 = 4294975772
- 229 + 4294975543 = 4294975772
- 379 + 4294975393 = 4294975772
- 433 + 4294975339 = 4294975772
- 853 + 4294974919 = 4294975772
- 859 + 4294974913 = 4294975772
- 1279 + 4294974493 = 4294975772
Showing the first eight; more decompositions exist.
