Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957888, here are decompositions:
- 29 + 4294957859 = 4294957888
- 47 + 4294957841 = 4294957888
- 107 + 4294957781 = 4294957888
- 191 + 4294957697 = 4294957888
- 449 + 4294957439 = 4294957888
- 491 + 4294957397 = 4294957888
- 569 + 4294957319 = 4294957888
- 821 + 4294957067 = 4294957888
Showing the first eight; more decompositions exist.
