Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609754, here are decompositions:
- 13 + 31609741 = 31609754
- 31 + 31609723 = 31609754
- 61 + 31609693 = 31609754
- 193 + 31609561 = 31609754
- 223 + 31609531 = 31609754
- 373 + 31609381 = 31609754
- 487 + 31609267 = 31609754
- 523 + 31609231 = 31609754
Showing the first eight; more decompositions exist.
