Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161632, here are decompositions:
- 5 + 161627 = 161632
- 41 + 161591 = 161632
- 59 + 161573 = 161632
- 71 + 161561 = 161632
- 89 + 161543 = 161632
- 101 + 161531 = 161632
- 173 + 161459 = 161632
- 179 + 161453 = 161632
Showing the first eight; more decompositions exist.
