Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529302, here are decompositions:

23 + 31529279 = 31529302
29 + 31529273 = 31529302
53 + 31529249 = 31529302
59 + 31529243 = 31529302
83 + 31529219 = 31529302
89 + 31529213 = 31529302
449 + 31528853 = 31529302
461 + 31528841 = 31529302

Showing the first eight; more decompositions exist.
