Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39504, here are decompositions:
- 5 + 39499 = 39504
- 43 + 39461 = 39504
- 53 + 39451 = 39504
- 61 + 39443 = 39504
- 107 + 39397 = 39504
- 131 + 39373 = 39504
- 137 + 39367 = 39504
- 163 + 39341 = 39504
Showing the first eight; more decompositions exist.
