Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478862, here are decompositions:
- 19 + 478843 = 478862
- 31 + 478831 = 478862
- 61 + 478801 = 478862
- 151 + 478711 = 478862
- 211 + 478651 = 478862
- 283 + 478579 = 478862
- 331 + 478531 = 478862
- 379 + 478483 = 478862
Showing the first eight; more decompositions exist.
