Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78162, here are decompositions:
- 5 + 78157 = 78162
- 23 + 78139 = 78162
- 41 + 78121 = 78162
- 61 + 78101 = 78162
- 83 + 78079 = 78162
- 103 + 78059 = 78162
- 113 + 78049 = 78162
- 131 + 78031 = 78162
Showing the first eight; more decompositions exist.
