Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49142, here are decompositions:
- 3 + 49139 = 49142
- 19 + 49123 = 49142
- 61 + 49081 = 49142
- 73 + 49069 = 49142
- 109 + 49033 = 49142
- 139 + 49003 = 49142
- 151 + 48991 = 49142
- 271 + 48871 = 49142
Showing the first eight; more decompositions exist.
