Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38290, here are decompositions:
- 3 + 38287 = 38290
- 17 + 38273 = 38290
- 29 + 38261 = 38290
- 53 + 38237 = 38290
- 59 + 38231 = 38290
- 71 + 38219 = 38290
- 89 + 38201 = 38290
- 101 + 38189 = 38290
Showing the first eight; more decompositions exist.
