Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957128, here are decompositions:
- 5 + 4294957123 = 4294957128
- 19 + 4294957109 = 4294957128
- 29 + 4294957099 = 4294957128
- 47 + 4294957081 = 4294957128
- 61 + 4294957067 = 4294957128
- 71 + 4294957057 = 4294957128
- 139 + 4294956989 = 4294957128
- 179 + 4294956949 = 4294957128
Showing the first eight; more decompositions exist.
