Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482692, here are decompositions:
- 11 + 2147482681 = 2147482692
- 29 + 2147482663 = 2147482692
- 31 + 2147482661 = 2147482692
- 71 + 2147482621 = 2147482692
- 101 + 2147482591 = 2147482692
- 109 + 2147482583 = 2147482692
- 191 + 2147482501 = 2147482692
- 211 + 2147482481 = 2147482692
Showing the first eight; more decompositions exist.
