Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020144, here are decompositions:
- 7 + 1020137 = 1020144
- 31 + 1020113 = 1020144
- 43 + 1020101 = 1020144
- 67 + 1020077 = 1020144
- 101 + 1020043 = 1020144
- 107 + 1020037 = 1020144
- 131 + 1020013 = 1020144
- 137 + 1020007 = 1020144
Showing the first eight; more decompositions exist.
