Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 32138, here are decompositions:
- 19 + 32119 = 32138
- 61 + 32077 = 32138
- 79 + 32059 = 32138
- 109 + 32029 = 32138
- 157 + 31981 = 32138
- 181 + 31957 = 32138
- 367 + 31771 = 32138
- 397 + 31741 = 32138
Showing the first eight; more decompositions exist.
