Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30418, here are decompositions:
- 29 + 30389 = 30418
- 71 + 30347 = 30418
- 149 + 30269 = 30418
- 257 + 30161 = 30418
- 281 + 30137 = 30418
- 347 + 30071 = 30418
- 359 + 30059 = 30418
- 389 + 30029 = 30418
Showing the first eight; more decompositions exist.
