Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957720, here are decompositions:
- 3 + 4294957717 = 4294957720
- 17 + 4294957703 = 4294957720
- 23 + 4294957697 = 4294957720
- 41 + 4294957679 = 4294957720
- 167 + 4294957553 = 4294957720
- 197 + 4294957523 = 4294957720
- 227 + 4294957493 = 4294957720
- 281 + 4294957439 = 4294957720
Showing the first eight; more decompositions exist.
