Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957948, here are decompositions:
- 5 + 4294957943 = 4294957948
- 89 + 4294957859 = 4294957948
- 107 + 4294957841 = 4294957948
- 167 + 4294957781 = 4294957948
- 251 + 4294957697 = 4294957948
- 269 + 4294957679 = 4294957948
- 509 + 4294957439 = 4294957948
- 599 + 4294957349 = 4294957948
Showing the first eight; more decompositions exist.
