Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506098, here are decompositions:
- 7 + 31506091 = 31506098
- 37 + 31506061 = 31506098
- 67 + 31506031 = 31506098
- 109 + 31505989 = 31506098
- 139 + 31505959 = 31506098
- 277 + 31505821 = 31506098
- 331 + 31505767 = 31506098
- 367 + 31505731 = 31506098
Showing the first eight; more decompositions exist.
