Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957920, here are decompositions:
- 17 + 4294957903 = 4294957920
- 59 + 4294957861 = 4294957920
- 61 + 4294957859 = 4294957920
- 67 + 4294957853 = 4294957920
- 79 + 4294957841 = 4294957920
- 139 + 4294957781 = 4294957920
- 167 + 4294957753 = 4294957920
- 191 + 4294957729 = 4294957920
Showing the first eight; more decompositions exist.
