Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40202, here are decompositions:
- 13 + 40189 = 40202
- 73 + 40129 = 40202
- 79 + 40123 = 40202
- 103 + 40099 = 40202
- 109 + 40093 = 40202
- 139 + 40063 = 40202
- 163 + 40039 = 40202
- 193 + 40009 = 40202
Showing the first eight; more decompositions exist.
