Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39138, here are decompositions:
- 5 + 39133 = 39138
- 19 + 39119 = 39138
- 31 + 39107 = 39138
- 41 + 39097 = 39138
- 59 + 39079 = 39138
- 97 + 39041 = 39138
- 167 + 38971 = 39138
- 179 + 38959 = 39138
Showing the first eight; more decompositions exist.
