Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489788, here are decompositions:
- 97 + 489691 = 489788
- 109 + 489679 = 489788
- 157 + 489631 = 489788
- 331 + 489457 = 489788
- 349 + 489439 = 489788
- 379 + 489409 = 489788
- 421 + 489367 = 489788
- 547 + 489241 = 489788
Showing the first eight; more decompositions exist.
