Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489288, here are decompositions:
- 5 + 489283 = 489288
- 31 + 489257 = 489288
- 47 + 489241 = 489288
- 71 + 489217 = 489288
- 97 + 489191 = 489288
- 109 + 489179 = 489288
- 127 + 489161 = 489288
- 131 + 489157 = 489288
Showing the first eight; more decompositions exist.
