Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 473990, here are decompositions:
- 3 + 473987 = 473990
- 19 + 473971 = 473990
- 37 + 473953 = 473990
- 61 + 473929 = 473990
- 67 + 473923 = 473990
- 79 + 473911 = 473990
- 103 + 473887 = 473990
- 151 + 473839 = 473990
Showing the first eight; more decompositions exist.
