Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957728, here are decompositions:
- 11 + 4294957717 = 4294957728
- 29 + 4294957699 = 4294957728
- 31 + 4294957697 = 4294957728
- 331 + 4294957397 = 4294957728
- 359 + 4294957369 = 4294957728
- 379 + 4294957349 = 4294957728
- 409 + 4294957319 = 4294957728
- 419 + 4294957309 = 4294957728
Showing the first eight; more decompositions exist.
