Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452522, here are decompositions:

5 + 31452517 = 31452522
29 + 31452493 = 31452522
41 + 31452481 = 31452522
61 + 31452461 = 31452522
71 + 31452451 = 31452522
103 + 31452419 = 31452522
181 + 31452341 = 31452522
239 + 31452283 = 31452522

Showing the first eight; more decompositions exist.
