Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147442818, here are decompositions:
- 7 + 2147442811 = 2147442818
- 67 + 2147442751 = 2147442818
- 181 + 2147442637 = 2147442818
- 307 + 2147442511 = 2147442818
- 331 + 2147442487 = 2147442818
- 349 + 2147442469 = 2147442818
- 487 + 2147442331 = 2147442818
- 541 + 2147442277 = 2147442818
Showing the first eight; more decompositions exist.
