Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527262, here are decompositions:

29 + 31527233 = 31527262
71 + 31527191 = 31527262
89 + 31527173 = 31527262
113 + 31527149 = 31527262
131 + 31527131 = 31527262
251 + 31527011 = 31527262
359 + 31526903 = 31527262
383 + 31526879 = 31527262

Showing the first eight; more decompositions exist.
