Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31974, here are decompositions:
- 11 + 31963 = 31974
- 17 + 31957 = 31974
- 67 + 31907 = 31974
- 83 + 31891 = 31974
- 101 + 31873 = 31974
- 127 + 31847 = 31974
- 157 + 31817 = 31974
- 181 + 31793 = 31974
Showing the first eight; more decompositions exist.
