Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529834, here are decompositions:

157 + 31529677 = 31529834
163 + 31529671 = 31529834
211 + 31529623 = 31529834
241 + 31529593 = 31529834
277 + 31529557 = 31529834
283 + 31529551 = 31529834
313 + 31529521 = 31529834
421 + 31529413 = 31529834

Showing the first eight; more decompositions exist.
