Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170142, here are decompositions:
- 19 + 170123 = 170142
- 31 + 170111 = 170142
- 41 + 170101 = 170142
- 43 + 170099 = 170142
- 61 + 170081 = 170142
- 79 + 170063 = 170142
- 113 + 170029 = 170142
- 139 + 170003 = 170142
Showing the first eight; more decompositions exist.
