Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482946, here are decompositions:
- 3 + 2147482943 = 2147482946
- 73 + 2147482873 = 2147482946
- 79 + 2147482867 = 2147482946
- 127 + 2147482819 = 2147482946
- 283 + 2147482663 = 2147482946
- 439 + 2147482507 = 2147482946
- 619 + 2147482327 = 2147482946
- 673 + 2147482273 = 2147482946
Showing the first eight; more decompositions exist.
