Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72162, here are decompositions:
- 23 + 72139 = 72162
- 53 + 72109 = 72162
- 59 + 72103 = 72162
- 61 + 72101 = 72162
- 71 + 72091 = 72162
- 73 + 72089 = 72162
- 89 + 72073 = 72162
- 109 + 72053 = 72162
Showing the first eight; more decompositions exist.
