Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546442, here are decompositions:
- 73 + 31546369 = 31546442
- 139 + 31546303 = 31546442
- 163 + 31546279 = 31546442
- 211 + 31546231 = 31546442
- 283 + 31546159 = 31546442
- 313 + 31546129 = 31546442
- 331 + 31546111 = 31546442
- 373 + 31546069 = 31546442
Showing the first eight; more decompositions exist.
