Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527660, here are decompositions:

83 + 31527577 = 31527660
127 + 31527533 = 31527660
137 + 31527523 = 31527660
139 + 31527521 = 31527660
163 + 31527497 = 31527660
179 + 31527481 = 31527660
271 + 31527389 = 31527660
317 + 31527343 = 31527660

Showing the first eight; more decompositions exist.
