Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481352, here are decompositions:
- 11 + 31481341 = 31481352
- 31 + 31481321 = 31481352
- 53 + 31481299 = 31481352
- 59 + 31481293 = 31481352
- 101 + 31481251 = 31481352
- 103 + 31481249 = 31481352
- 113 + 31481239 = 31481352
- 151 + 31481201 = 31481352
Showing the first eight; more decompositions exist.
