Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147423318, here are decompositions:
- 37 + 2147423281 = 2147423318
- 181 + 2147423137 = 2147423318
- 331 + 2147422987 = 2147423318
- 421 + 2147422897 = 2147423318
- 457 + 2147422861 = 2147423318
- 499 + 2147422819 = 2147423318
- 541 + 2147422777 = 2147423318
- 571 + 2147422747 = 2147423318
Showing the first eight; more decompositions exist.
