Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162162, here are decompositions:
- 19 + 162143 = 162162
- 43 + 162119 = 162162
- 53 + 162109 = 162162
- 71 + 162091 = 162162
- 83 + 162079 = 162162
- 103 + 162059 = 162162
- 109 + 162053 = 162162
- 151 + 162011 = 162162
Showing the first eight; more decompositions exist.
