Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020162, here are decompositions:
- 5 + 1020157 = 1020162
- 19 + 1020143 = 1020162
- 53 + 1020109 = 1020162
- 61 + 1020101 = 1020162
- 83 + 1020079 = 1020162
- 103 + 1020059 = 1020162
- 113 + 1020049 = 1020162
- 139 + 1020023 = 1020162
Showing the first eight; more decompositions exist.
