Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294962720, here are decompositions:
- 17 + 4294962703 = 4294962720
- 29 + 4294962691 = 4294962720
- 31 + 4294962689 = 4294962720
- 67 + 4294962653 = 4294962720
- 79 + 4294962641 = 4294962720
- 101 + 4294962619 = 4294962720
- 131 + 4294962589 = 4294962720
- 179 + 4294962541 = 4294962720
Showing the first eight; more decompositions exist.
