Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958864, here are decompositions:
- 3 + 4294958861 = 4294958864
- 73 + 4294958791 = 4294958864
- 337 + 4294958527 = 4294958864
- 397 + 4294958467 = 4294958864
- 421 + 4294958443 = 4294958864
- 463 + 4294958401 = 4294958864
- 607 + 4294958257 = 4294958864
- 733 + 4294958131 = 4294958864
Showing the first eight; more decompositions exist.
