Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162156, here are decompositions:
- 13 + 162143 = 162156
- 37 + 162119 = 162156
- 47 + 162109 = 162156
- 97 + 162059 = 162156
- 103 + 162053 = 162156
- 139 + 162017 = 162156
- 149 + 162007 = 162156
- 157 + 161999 = 162156
Showing the first eight; more decompositions exist.
