Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021202, here are decompositions:
- 3 + 1021199 = 1021202
- 19 + 1021183 = 1021202
- 43 + 1021159 = 1021202
- 73 + 1021129 = 1021202
- 79 + 1021123 = 1021202
- 109 + 1021093 = 1021202
- 211 + 1020991 = 1021202
- 223 + 1020979 = 1021202
Showing the first eight; more decompositions exist.
