Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939642, here are decompositions:
- 19 + 939623 = 939642
- 29 + 939613 = 939642
- 31 + 939611 = 939642
- 43 + 939599 = 939642
- 61 + 939581 = 939642
- 131 + 939511 = 939642
- 173 + 939469 = 939642
- 191 + 939451 = 939642
Showing the first eight; more decompositions exist.
