Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540350, here are decompositions:

7 + 31540343 = 31540350
11 + 31540339 = 31540350
41 + 31540309 = 31540350
53 + 31540297 = 31540350
89 + 31540261 = 31540350
109 + 31540241 = 31540350
137 + 31540213 = 31540350
139 + 31540211 = 31540350

Showing the first eight; more decompositions exist.
