Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961664, here are decompositions:
- 41 + 4294961623 = 4294961664
- 67 + 4294961597 = 4294961664
- 137 + 4294961527 = 4294961664
- 157 + 4294961507 = 4294961664
- 181 + 4294961483 = 4294961664
- 197 + 4294961467 = 4294961664
- 211 + 4294961453 = 4294961664
- 263 + 4294961401 = 4294961664
Showing the first eight; more decompositions exist.
