Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575952, here are decompositions:
- 29 + 31575923 = 31575952
- 53 + 31575899 = 31575952
- 59 + 31575893 = 31575952
- 71 + 31575881 = 31575952
- 113 + 31575839 = 31575952
- 281 + 31575671 = 31575952
- 311 + 31575641 = 31575952
- 389 + 31575563 = 31575952
Showing the first eight; more decompositions exist.
