Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74154, here are decompositions:
- 5 + 74149 = 74154
- 11 + 74143 = 74154
- 23 + 74131 = 74154
- 53 + 74101 = 74154
- 61 + 74093 = 74154
- 83 + 74071 = 74154
- 103 + 74051 = 74154
- 107 + 74047 = 74154
Showing the first eight; more decompositions exist.
