Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482642, here are decompositions:
- 59 + 2147482583 = 2147482642
- 233 + 2147482409 = 2147482642
- 281 + 2147482361 = 2147482642
- 293 + 2147482349 = 2147482642
- 419 + 2147482223 = 2147482642
- 521 + 2147482121 = 2147482642
- 743 + 2147481899 = 2147482642
- 1013 + 2147481629 = 2147482642
Showing the first eight; more decompositions exist.
