Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522852, here are decompositions:

5 + 31522847 = 31522852
29 + 31522823 = 31522852
239 + 31522613 = 31522852
269 + 31522583 = 31522852
311 + 31522541 = 31522852
359 + 31522493 = 31522852
401 + 31522451 = 31522852
419 + 31522433 = 31522852

Showing the first eight; more decompositions exist.
