Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489270, here are decompositions:
- 7 + 489263 = 489270
- 13 + 489257 = 489270
- 29 + 489241 = 489270
- 31 + 489239 = 489270
- 53 + 489217 = 489270
- 73 + 489197 = 489270
- 79 + 489191 = 489270
- 109 + 489161 = 489270
Showing the first eight; more decompositions exist.
