Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102162, here are decompositions:
- 13 + 102149 = 102162
- 23 + 102139 = 102162
- 41 + 102121 = 102162
- 59 + 102103 = 102162
- 61 + 102101 = 102162
- 83 + 102079 = 102162
- 101 + 102061 = 102162
- 103 + 102059 = 102162
Showing the first eight; more decompositions exist.
