Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161070, here are decompositions:
- 11 + 161059 = 161070
- 17 + 161053 = 161070
- 23 + 161047 = 161070
- 31 + 161039 = 161070
- 37 + 161033 = 161070
- 53 + 161017 = 161070
- 61 + 161009 = 161070
- 73 + 160997 = 161070
Showing the first eight; more decompositions exist.
