Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541220, here are decompositions:
- 41 + 31541179 = 31541220
- 47 + 31541173 = 31541220
- 59 + 31541161 = 31541220
- 79 + 31541141 = 31541220
- 103 + 31541117 = 31541220
- 107 + 31541113 = 31541220
- 149 + 31541071 = 31541220
- 173 + 31541047 = 31541220
Showing the first eight; more decompositions exist.
