Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527292, here are decompositions:

59 + 31527233 = 31527292
101 + 31527191 = 31527292
149 + 31527143 = 31527292
281 + 31527011 = 31527292
353 + 31526939 = 31527292
389 + 31526903 = 31527292
521 + 31526771 = 31527292
569 + 31526723 = 31527292

Showing the first eight; more decompositions exist.
