Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957138, here are decompositions:
- 29 + 4294957109 = 4294957138
- 71 + 4294957067 = 4294957138
- 149 + 4294956989 = 4294957138
- 257 + 4294956881 = 4294957138
- 419 + 4294956719 = 4294957138
- 449 + 4294956689 = 4294957138
- 467 + 4294956671 = 4294957138
- 509 + 4294956629 = 4294957138
Showing the first eight; more decompositions exist.
