Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508068, here are decompositions:
- 29 + 31508039 = 31508068
- 41 + 31508027 = 31508068
- 167 + 31507901 = 31508068
- 191 + 31507877 = 31508068
- 281 + 31507787 = 31508068
- 359 + 31507709 = 31508068
- 401 + 31507667 = 31508068
- 461 + 31507607 = 31508068
Showing the first eight; more decompositions exist.
