Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49128, here are decompositions:
- 5 + 49123 = 49128
- 7 + 49121 = 49128
- 11 + 49117 = 49128
- 19 + 49109 = 49128
- 47 + 49081 = 49128
- 59 + 49069 = 49128
- 71 + 49057 = 49128
- 97 + 49031 = 49128
Showing the first eight; more decompositions exist.
