Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985542, here are decompositions:
- 11 + 985531 = 985542
- 13 + 985529 = 985542
- 23 + 985519 = 985542
- 43 + 985499 = 985542
- 59 + 985483 = 985542
- 71 + 985471 = 985542
- 79 + 985463 = 985542
- 109 + 985433 = 985542
Showing the first eight; more decompositions exist.
