Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998970, here are decompositions:
- 13 + 998957 = 998970
- 19 + 998951 = 998970
- 23 + 998947 = 998970
- 29 + 998941 = 998970
- 43 + 998927 = 998970
- 53 + 998917 = 998970
- 61 + 998909 = 998970
- 73 + 998897 = 998970
Showing the first eight; more decompositions exist.
