Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39690, here are decompositions:
- 11 + 39679 = 39690
- 19 + 39671 = 39690
- 23 + 39667 = 39690
- 31 + 39659 = 39690
- 59 + 39631 = 39690
- 67 + 39623 = 39690
- 71 + 39619 = 39690
- 83 + 39607 = 39690
Showing the first eight; more decompositions exist.
