Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038312, here are decompositions:
- 5 + 1038307 = 1038312
- 43 + 1038269 = 1038312
- 53 + 1038259 = 1038312
- 59 + 1038253 = 1038312
- 61 + 1038251 = 1038312
- 101 + 1038211 = 1038312
- 103 + 1038209 = 1038312
- 109 + 1038203 = 1038312
Showing the first eight; more decompositions exist.
