Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473192, here are decompositions:
- 5 + 2147473187 = 2147473192
- 41 + 2147473151 = 2147473192
- 71 + 2147473121 = 2147473192
- 131 + 2147473061 = 2147473192
- 233 + 2147472959 = 2147473192
- 269 + 2147472923 = 2147473192
- 479 + 2147472713 = 2147473192
- 503 + 2147472689 = 2147473192
Showing the first eight; more decompositions exist.
