Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527472, here are decompositions:

59 + 31527413 = 31527472
83 + 31527389 = 31527472
149 + 31527323 = 31527472
239 + 31527233 = 31527472
281 + 31527191 = 31527472
461 + 31527011 = 31527472
569 + 31526903 = 31527472
593 + 31526879 = 31527472

Showing the first eight; more decompositions exist.
