Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527702, here are decompositions:

5 + 31527697 = 31527702
13 + 31527689 = 31527702
43 + 31527659 = 31527702
179 + 31527523 = 31527702
181 + 31527521 = 31527702
211 + 31527491 = 31527702
313 + 31527389 = 31527702
359 + 31527343 = 31527702

Showing the first eight; more decompositions exist.
