Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43122, here are decompositions:
- 5 + 43117 = 43122
- 19 + 43103 = 43122
- 29 + 43093 = 43122
- 59 + 43063 = 43122
- 71 + 43051 = 43122
- 73 + 43049 = 43122
- 103 + 43019 = 43122
- 109 + 43013 = 43122
Showing the first eight; more decompositions exist.
