Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473738, here are decompositions:
- 5 + 2147473733 = 2147473738
- 41 + 2147473697 = 2147473738
- 251 + 2147473487 = 2147473738
- 269 + 2147473469 = 2147473738
- 521 + 2147473217 = 2147473738
- 587 + 2147473151 = 2147473738
- 617 + 2147473121 = 2147473738
- 677 + 2147473061 = 2147473738
Showing the first eight; more decompositions exist.
