Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476380, here are decompositions:
- 13 + 2147476367 = 2147476380
- 53 + 2147476327 = 2147476380
- 59 + 2147476321 = 2147476380
- 89 + 2147476291 = 2147476380
- 131 + 2147476249 = 2147476380
- 197 + 2147476183 = 2147476380
- 211 + 2147476169 = 2147476380
- 239 + 2147476141 = 2147476380
Showing the first eight; more decompositions exist.
