Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31932, here are decompositions:
- 41 + 31891 = 31932
- 59 + 31873 = 31932
- 73 + 31859 = 31932
- 83 + 31849 = 31932
- 139 + 31793 = 31932
- 163 + 31769 = 31932
- 181 + 31751 = 31932
- 191 + 31741 = 31932
Showing the first eight; more decompositions exist.
