Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527786, here are decompositions:

5 + 31527781 = 31527786
83 + 31527703 = 31527786
89 + 31527697 = 31527786
97 + 31527689 = 31527786
109 + 31527677 = 31527786
127 + 31527659 = 31527786
263 + 31527523 = 31527786
373 + 31527413 = 31527786

Showing the first eight; more decompositions exist.
