Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541210, here are decompositions:

31 + 31541179 = 31541210
37 + 31541173 = 31541210
97 + 31541113 = 31541210
109 + 31541101 = 31541210
139 + 31541071 = 31541210
163 + 31541047 = 31541210
193 + 31541017 = 31541210
271 + 31540939 = 31541210

Showing the first eight; more decompositions exist.
