Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39402, here are decompositions:
- 5 + 39397 = 39402
- 19 + 39383 = 39402
- 29 + 39373 = 39402
- 31 + 39371 = 39402
- 43 + 39359 = 39402
- 59 + 39343 = 39402
- 61 + 39341 = 39402
- 79 + 39323 = 39402
Showing the first eight; more decompositions exist.
