Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7182, here are decompositions:
- 5 + 7177 = 7182
- 23 + 7159 = 7182
- 31 + 7151 = 7182
- 53 + 7129 = 7182
- 61 + 7121 = 7182
- 73 + 7109 = 7182
- 79 + 7103 = 7182
- 103 + 7079 = 7182
Showing the first eight; more decompositions exist.
