Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506182, here are decompositions:
- 79 + 31506103 = 31506182
- 151 + 31506031 = 31506182
- 193 + 31505989 = 31506182
- 199 + 31505983 = 31506182
- 223 + 31505959 = 31506182
- 373 + 31505809 = 31506182
- 523 + 31505659 = 31506182
- 613 + 31505569 = 31506182
Showing the first eight; more decompositions exist.
