Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579226, here are decompositions:
- 13 + 31579213 = 31579226
- 97 + 31579129 = 31579226
- 127 + 31579099 = 31579226
- 139 + 31579087 = 31579226
- 223 + 31579003 = 31579226
- 277 + 31578949 = 31579226
- 307 + 31578919 = 31579226
- 439 + 31578787 = 31579226
Showing the first eight; more decompositions exist.
