Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478590, here are decompositions:
- 11 + 478579 = 478590
- 17 + 478573 = 478590
- 19 + 478571 = 478590
- 59 + 478531 = 478590
- 67 + 478523 = 478590
- 97 + 478493 = 478590
- 107 + 478483 = 478590
- 109 + 478481 = 478590
Showing the first eight; more decompositions exist.
