Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527562, here are decompositions:

29 + 31527533 = 31527562
41 + 31527521 = 31527562
71 + 31527491 = 31527562
149 + 31527413 = 31527562
173 + 31527389 = 31527562
239 + 31527323 = 31527562
251 + 31527311 = 31527562
389 + 31527173 = 31527562

Showing the first eight; more decompositions exist.
