Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542470, here are decompositions:
- 13 + 31542457 = 31542470
- 31 + 31542439 = 31542470
- 73 + 31542397 = 31542470
- 79 + 31542391 = 31542470
- 97 + 31542373 = 31542470
- 241 + 31542229 = 31542470
- 307 + 31542163 = 31542470
- 367 + 31542103 = 31542470
Showing the first eight; more decompositions exist.
