Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161706, here are decompositions:
- 23 + 161683 = 161706
- 47 + 161659 = 161706
- 67 + 161639 = 161706
- 79 + 161627 = 161706
- 107 + 161599 = 161706
- 137 + 161569 = 161706
- 163 + 161543 = 161706
- 179 + 161527 = 161706
Showing the first eight; more decompositions exist.
