Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482742, here are decompositions:
- 3 + 2147482739 = 2147482742
- 61 + 2147482681 = 2147482742
- 79 + 2147482663 = 2147482742
- 151 + 2147482591 = 2147482742
- 241 + 2147482501 = 2147482742
- 661 + 2147482081 = 2147482742
- 859 + 2147481883 = 2147482742
- 1069 + 2147481673 = 2147482742
Showing the first eight; more decompositions exist.
