Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294959872, here are decompositions:
- 3 + 4294959869 = 4294959872
- 13 + 4294959859 = 4294959872
- 199 + 4294959673 = 4294959872
- 331 + 4294959541 = 4294959872
- 433 + 4294959439 = 4294959872
- 439 + 4294959433 = 4294959872
- 571 + 4294959301 = 4294959872
- 613 + 4294959259 = 4294959872
Showing the first eight; more decompositions exist.
