Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482628, here are decompositions:
- 7 + 2147482621 = 2147482628
- 37 + 2147482591 = 2147482628
- 127 + 2147482501 = 2147482628
- 211 + 2147482417 = 2147482628
- 337 + 2147482291 = 2147482628
- 397 + 2147482231 = 2147482628
- 547 + 2147482081 = 2147482628
- 607 + 2147482021 = 2147482628
Showing the first eight; more decompositions exist.
