Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39672, here are decompositions:
- 5 + 39667 = 39672
- 13 + 39659 = 39672
- 41 + 39631 = 39672
- 53 + 39619 = 39672
- 103 + 39569 = 39672
- 109 + 39563 = 39672
- 131 + 39541 = 39672
- 151 + 39521 = 39672
Showing the first eight; more decompositions exist.
