Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527654, here are decompositions:

71 + 31527583 = 31527654
113 + 31527541 = 31527654
131 + 31527523 = 31527654
157 + 31527497 = 31527654
163 + 31527491 = 31527654
173 + 31527481 = 31527654
241 + 31527413 = 31527654
311 + 31527343 = 31527654

Showing the first eight; more decompositions exist.
