Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489370, here are decompositions:
- 3 + 489367 = 489370
- 41 + 489329 = 489370
- 71 + 489299 = 489370
- 107 + 489263 = 489370
- 113 + 489257 = 489370
- 131 + 489239 = 489370
- 173 + 489197 = 489370
- 179 + 489191 = 489370
Showing the first eight; more decompositions exist.
