Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538246, here are decompositions:
- 7 + 31538239 = 31538246
- 43 + 31538203 = 31538246
- 109 + 31538137 = 31538246
- 139 + 31538107 = 31538246
- 193 + 31538053 = 31538246
- 199 + 31538047 = 31538246
- 307 + 31537939 = 31538246
- 409 + 31537837 = 31538246
Showing the first eight; more decompositions exist.
