Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482948, here are decompositions:
- 5 + 2147482943 = 2147482948
- 11 + 2147482937 = 2147482948
- 71 + 2147482877 = 2147482948
- 89 + 2147482859 = 2147482948
- 131 + 2147482817 = 2147482948
- 137 + 2147482811 = 2147482948
- 251 + 2147482697 = 2147482948
- 467 + 2147482481 = 2147482948
Showing the first eight; more decompositions exist.
