Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161762, here are decompositions:
- 19 + 161743 = 161762
- 31 + 161731 = 161762
- 79 + 161683 = 161762
- 103 + 161659 = 161762
- 151 + 161611 = 161762
- 163 + 161599 = 161762
- 193 + 161569 = 161762
- 199 + 161563 = 161762
Showing the first eight; more decompositions exist.
