Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90378, here are decompositions:
- 5 + 90373 = 90378
- 7 + 90371 = 90378
- 19 + 90359 = 90378
- 89 + 90289 = 90378
- 97 + 90281 = 90378
- 107 + 90271 = 90378
- 131 + 90247 = 90378
- 139 + 90239 = 90378
Showing the first eight; more decompositions exist.
