Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161736, here are decompositions:
- 5 + 161731 = 161736
- 7 + 161729 = 161736
- 19 + 161717 = 161736
- 53 + 161683 = 161736
- 97 + 161639 = 161736
- 109 + 161627 = 161736
- 137 + 161599 = 161736
- 163 + 161573 = 161736
Showing the first eight; more decompositions exist.
