Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39444, here are decompositions:
- 5 + 39439 = 39444
- 47 + 39397 = 39444
- 61 + 39383 = 39444
- 71 + 39373 = 39444
- 73 + 39371 = 39444
- 101 + 39343 = 39444
- 103 + 39341 = 39444
- 127 + 39317 = 39444
Showing the first eight; more decompositions exist.
