Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49146, here are decompositions:
- 7 + 49139 = 49146
- 23 + 49123 = 49146
- 29 + 49117 = 49146
- 37 + 49109 = 49146
- 43 + 49103 = 49146
- 89 + 49057 = 49146
- 103 + 49043 = 49146
- 109 + 49037 = 49146
Showing the first eight; more decompositions exist.
