Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989628, here are decompositions:
- 5 + 989623 = 989628
- 47 + 989581 = 989628
- 67 + 989561 = 989628
- 71 + 989557 = 989628
- 149 + 989479 = 989628
- 151 + 989477 = 989628
- 251 + 989377 = 989628
- 281 + 989347 = 989628
Showing the first eight; more decompositions exist.
