Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482940, here are decompositions:
- 3 + 2147482937 = 2147482940
- 19 + 2147482921 = 2147482940
- 67 + 2147482873 = 2147482940
- 73 + 2147482867 = 2147482940
- 139 + 2147482801 = 2147482940
- 277 + 2147482663 = 2147482940
- 349 + 2147482591 = 2147482940
- 433 + 2147482507 = 2147482940
Showing the first eight; more decompositions exist.
