Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529292, here are decompositions:

13 + 31529279 = 31529292
19 + 31529273 = 31529292
23 + 31529269 = 31529292
43 + 31529249 = 31529292
73 + 31529219 = 31529292
79 + 31529213 = 31529292
211 + 31529081 = 31529292
239 + 31529053 = 31529292

Showing the first eight; more decompositions exist.
