Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529382, here are decompositions:

23 + 31529359 = 31529382
29 + 31529353 = 31529382
61 + 31529321 = 31529382
103 + 31529279 = 31529382
109 + 31529273 = 31529382
113 + 31529269 = 31529382
139 + 31529243 = 31529382
163 + 31529219 = 31529382

Showing the first eight; more decompositions exist.
