Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426220, here are decompositions:
- 13 + 2147426207 = 2147426220
- 53 + 2147426167 = 2147426220
- 59 + 2147426161 = 2147426220
- 61 + 2147426159 = 2147426220
- 67 + 2147426153 = 2147426220
- 73 + 2147426147 = 2147426220
- 83 + 2147426137 = 2147426220
- 103 + 2147426117 = 2147426220
Showing the first eight; more decompositions exist.
