Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427480, here are decompositions:
- 7 + 2147427473 = 2147427480
- 53 + 2147427427 = 2147427480
- 83 + 2147427397 = 2147427480
- 251 + 2147427229 = 2147427480
- 271 + 2147427209 = 2147427480
- 307 + 2147427173 = 2147427480
- 311 + 2147427169 = 2147427480
- 389 + 2147427091 = 2147427480
Showing the first eight; more decompositions exist.
