Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39140, here are decompositions:
- 7 + 39133 = 39140
- 37 + 39103 = 39140
- 43 + 39097 = 39140
- 61 + 39079 = 39140
- 97 + 39043 = 39140
- 163 + 38977 = 39140
- 181 + 38959 = 39140
- 223 + 38917 = 39140
Showing the first eight; more decompositions exist.
