Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529852, here are decompositions:

103 + 31529749 = 31529852
181 + 31529671 = 31529852
223 + 31529629 = 31529852
229 + 31529623 = 31529852
313 + 31529539 = 31529852
331 + 31529521 = 31529852
373 + 31529479 = 31529852
421 + 31529431 = 31529852

Showing the first eight; more decompositions exist.
