Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427890, here are decompositions:
- 7 + 2147427883 = 2147427890
- 31 + 2147427859 = 2147427890
- 43 + 2147427847 = 2147427890
- 109 + 2147427781 = 2147427890
- 163 + 2147427727 = 2147427890
- 211 + 2147427679 = 2147427890
- 463 + 2147427427 = 2147427890
- 661 + 2147427229 = 2147427890
Showing the first eight; more decompositions exist.
