Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562072, here are decompositions:
- 19 + 31562053 = 31562072
- 79 + 31561993 = 31562072
- 103 + 31561969 = 31562072
- 271 + 31561801 = 31562072
- 349 + 31561723 = 31562072
- 379 + 31561693 = 31562072
- 499 + 31561573 = 31562072
- 523 + 31561549 = 31562072
Showing the first eight; more decompositions exist.
