Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72182, here are decompositions:
- 13 + 72169 = 72182
- 43 + 72139 = 72182
- 73 + 72109 = 72182
- 79 + 72103 = 72182
- 109 + 72073 = 72182
- 139 + 72043 = 72182
- 151 + 72031 = 72182
- 163 + 72019 = 72182
Showing the first eight; more decompositions exist.
