Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646442, here are decompositions:
- 41 + 8646401 = 8646442
- 53 + 8646389 = 8646442
- 113 + 8646329 = 8646442
- 149 + 8646293 = 8646442
- 173 + 8646269 = 8646442
- 383 + 8646059 = 8646442
- 461 + 8645981 = 8646442
- 593 + 8645849 = 8646442
Showing the first eight; more decompositions exist.
