Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427818, here are decompositions:
- 37 + 2147427781 = 2147427818
- 139 + 2147427679 = 2147427818
- 421 + 2147427397 = 2147427818
- 661 + 2147427157 = 2147427818
- 727 + 2147427091 = 2147427818
- 829 + 2147426989 = 2147427818
- 997 + 2147426821 = 2147427818
- 1291 + 2147426527 = 2147427818
Showing the first eight; more decompositions exist.
