Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124578, here are decompositions:
- 11 + 124567 = 124578
- 17 + 124561 = 124578
- 37 + 124541 = 124578
- 89 + 124489 = 124578
- 101 + 124477 = 124578
- 107 + 124471 = 124578
- 131 + 124447 = 124578
- 149 + 124429 = 124578
Showing the first eight; more decompositions exist.
