Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529202, here are decompositions:

53 + 31529149 = 31529202
113 + 31529089 = 31529202
149 + 31529053 = 31529202
233 + 31528969 = 31529202
293 + 31528909 = 31529202
349 + 31528853 = 31529202
359 + 31528843 = 31529202
379 + 31528823 = 31529202

Showing the first eight; more decompositions exist.
