Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527836, here are decompositions:

7 + 31527829 = 31527836
19 + 31527817 = 31527836
127 + 31527709 = 31527836
139 + 31527697 = 31527836
313 + 31527523 = 31527836
337 + 31527499 = 31527836
643 + 31527193 = 31527836
727 + 31527109 = 31527836

Showing the first eight; more decompositions exist.
