Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30402, here are decompositions:
- 11 + 30391 = 30402
- 13 + 30389 = 30402
- 61 + 30341 = 30402
- 79 + 30323 = 30402
- 83 + 30319 = 30402
- 89 + 30313 = 30402
- 109 + 30293 = 30402
- 131 + 30271 = 30402
Showing the first eight; more decompositions exist.
