Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550904, here are decompositions:
- 37 + 31550867 = 31550904
- 53 + 31550851 = 31550904
- 67 + 31550837 = 31550904
- 71 + 31550833 = 31550904
- 97 + 31550807 = 31550904
- 101 + 31550803 = 31550904
- 103 + 31550801 = 31550904
- 107 + 31550797 = 31550904
Showing the first eight; more decompositions exist.
