Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162756, here are decompositions:
- 5 + 162751 = 162756
- 7 + 162749 = 162756
- 17 + 162739 = 162756
- 29 + 162727 = 162756
- 43 + 162713 = 162756
- 47 + 162709 = 162756
- 53 + 162703 = 162756
- 73 + 162683 = 162756
Showing the first eight; more decompositions exist.
