Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478608, here are decompositions:
- 5 + 478603 = 478608
- 19 + 478589 = 478608
- 29 + 478579 = 478608
- 37 + 478571 = 478608
- 127 + 478481 = 478608
- 149 + 478459 = 478608
- 157 + 478451 = 478608
- 167 + 478441 = 478608
Showing the first eight; more decompositions exist.
