Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427938, here are decompositions:
- 31 + 2147427907 = 2147427938
- 37 + 2147427901 = 2147427938
- 79 + 2147427859 = 2147427938
- 157 + 2147427781 = 2147427938
- 211 + 2147427727 = 2147427938
- 541 + 2147427397 = 2147427938
- 709 + 2147427229 = 2147427938
- 769 + 2147427169 = 2147427938
Showing the first eight; more decompositions exist.
