Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550952, here are decompositions:
- 5 + 31550947 = 31550952
- 29 + 31550923 = 31550952
- 31 + 31550921 = 31550952
- 73 + 31550879 = 31550952
- 101 + 31550851 = 31550952
- 149 + 31550803 = 31550952
- 151 + 31550801 = 31550952
- 229 + 31550723 = 31550952
Showing the first eight; more decompositions exist.
