Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31846, here are decompositions:
- 29 + 31817 = 31846
- 47 + 31799 = 31846
- 53 + 31793 = 31846
- 179 + 31667 = 31846
- 197 + 31649 = 31846
- 239 + 31607 = 31846
- 263 + 31583 = 31846
- 449 + 31397 = 31846
Showing the first eight; more decompositions exist.
