Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146140, here are decompositions:
- 23 + 146117 = 146140
- 41 + 146099 = 146140
- 47 + 146093 = 146140
- 83 + 146057 = 146140
- 89 + 146051 = 146140
- 107 + 146033 = 146140
- 131 + 146009 = 146140
- 149 + 145991 = 146140
Showing the first eight; more decompositions exist.
