Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74578, here are decompositions:
- 5 + 74573 = 74578
- 11 + 74567 = 74578
- 17 + 74561 = 74578
- 47 + 74531 = 74578
- 71 + 74507 = 74578
- 89 + 74489 = 74578
- 107 + 74471 = 74578
- 137 + 74441 = 74578
Showing the first eight; more decompositions exist.
