Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427476, here are decompositions:
- 3 + 2147427473 = 2147427476
- 79 + 2147427397 = 2147427476
- 307 + 2147427169 = 2147427476
- 433 + 2147427043 = 2147427476
- 487 + 2147426989 = 2147427476
- 853 + 2147426623 = 2147427476
- 919 + 2147426557 = 2147427476
- 1009 + 2147426467 = 2147427476
Showing the first eight; more decompositions exist.
