Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562192, here are decompositions:
- 73 + 31562119 = 31562192
- 139 + 31562053 = 31562192
- 199 + 31561993 = 31562192
- 223 + 31561969 = 31562192
- 439 + 31561753 = 31562192
- 463 + 31561729 = 31562192
- 499 + 31561693 = 31562192
- 523 + 31561669 = 31562192
Showing the first eight; more decompositions exist.
