Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487440, here are decompositions:
- 17 + 33487423 = 33487440
- 23 + 33487417 = 33487440
- 47 + 33487393 = 33487440
- 53 + 33487387 = 33487440
- 97 + 33487343 = 33487440
- 127 + 33487313 = 33487440
- 131 + 33487309 = 33487440
- 139 + 33487301 = 33487440
Showing the first eight; more decompositions exist.
