Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31754, here are decompositions:
- 3 + 31751 = 31754
- 13 + 31741 = 31754
- 31 + 31723 = 31754
- 67 + 31687 = 31754
- 97 + 31657 = 31754
- 127 + 31627 = 31754
- 181 + 31573 = 31754
- 211 + 31543 = 31754
Showing the first eight; more decompositions exist.
