Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525292, here are decompositions:

3 + 31525289 = 31525292
13 + 31525279 = 31525292
31 + 31525261 = 31525292
79 + 31525213 = 31525292
109 + 31525183 = 31525292
499 + 31524793 = 31525292
571 + 31524721 = 31525292
619 + 31524673 = 31525292

Showing the first eight; more decompositions exist.
