Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31926, here are decompositions:
- 19 + 31907 = 31926
- 43 + 31883 = 31926
- 53 + 31873 = 31926
- 67 + 31859 = 31926
- 79 + 31847 = 31926
- 109 + 31817 = 31926
- 127 + 31799 = 31926
- 157 + 31769 = 31926
Showing the first eight; more decompositions exist.
