Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39472, here are decompositions:
- 11 + 39461 = 39472
- 29 + 39443 = 39472
- 53 + 39419 = 39472
- 89 + 39383 = 39472
- 101 + 39371 = 39472
- 113 + 39359 = 39472
- 131 + 39341 = 39472
- 149 + 39323 = 39472
Showing the first eight; more decompositions exist.
