Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989478, here are decompositions:
- 11 + 989467 = 989478
- 37 + 989441 = 989478
- 59 + 989419 = 989478
- 67 + 989411 = 989478
- 97 + 989381 = 989478
- 101 + 989377 = 989478
- 131 + 989347 = 989478
- 137 + 989341 = 989478
Showing the first eight; more decompositions exist.
