Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448952, here are decompositions:
- 43 + 31448909 = 31448952
- 53 + 31448899 = 31448952
- 61 + 31448891 = 31448952
- 89 + 31448863 = 31448952
- 113 + 31448839 = 31448952
- 131 + 31448821 = 31448952
- 149 + 31448803 = 31448952
- 211 + 31448741 = 31448952
Showing the first eight; more decompositions exist.
