Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527352, here are decompositions:

29 + 31527323 = 31527352
41 + 31527311 = 31527352
179 + 31527173 = 31527352
431 + 31526921 = 31527352
449 + 31526903 = 31527352
599 + 31526753 = 31527352
683 + 31526669 = 31527352
719 + 31526633 = 31527352

Showing the first eight; more decompositions exist.
