Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592, here are decompositions:
- 19 + 31573 = 31592
- 61 + 31531 = 31592
- 79 + 31513 = 31592
- 103 + 31489 = 31592
- 199 + 31393 = 31592
- 271 + 31321 = 31592
- 373 + 31219 = 31592
- 409 + 31183 = 31592
Showing the first eight; more decompositions exist.
