Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961640, here are decompositions:
- 17 + 4294961623 = 4294961640
- 43 + 4294961597 = 4294961640
- 61 + 4294961579 = 4294961640
- 113 + 4294961527 = 4294961640
- 157 + 4294961483 = 4294961640
- 173 + 4294961467 = 4294961640
- 191 + 4294961449 = 4294961640
- 239 + 4294961401 = 4294961640
Showing the first eight; more decompositions exist.
