Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522920, here are decompositions:
- 19 + 31522901 = 31522920
- 31 + 31522889 = 31522920
- 47 + 31522873 = 31522920
- 73 + 31522847 = 31522920
- 97 + 31522823 = 31522920
- 173 + 31522747 = 31522920
- 227 + 31522693 = 31522920
- 251 + 31522669 = 31522920
Showing the first eight; more decompositions exist.
