Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39172, here are decompositions:
- 11 + 39161 = 39172
- 53 + 39119 = 39172
- 59 + 39113 = 39172
- 83 + 39089 = 39172
- 131 + 39041 = 39172
- 149 + 39023 = 39172
- 179 + 38993 = 39172
- 239 + 38933 = 39172
Showing the first eight; more decompositions exist.
