Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162648, here are decompositions:
- 7 + 162641 = 162648
- 19 + 162629 = 162648
- 37 + 162611 = 162648
- 47 + 162601 = 162648
- 71 + 162577 = 162648
- 131 + 162517 = 162648
- 149 + 162499 = 162648
- 191 + 162457 = 162648
Showing the first eight; more decompositions exist.
