Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478938, here are decompositions:
- 7 + 478931 = 478938
- 11 + 478927 = 478938
- 37 + 478901 = 478938
- 41 + 478897 = 478938
- 59 + 478879 = 478938
- 67 + 478871 = 478938
- 107 + 478831 = 478938
- 127 + 478811 = 478938
Showing the first eight; more decompositions exist.
