Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538036, here are decompositions:

3 + 31538033 = 31538036
7 + 31538029 = 31538036
37 + 31537999 = 31538036
97 + 31537939 = 31538036
193 + 31537843 = 31538036
199 + 31537837 = 31538036
349 + 31537687 = 31538036
433 + 31537603 = 31538036

Showing the first eight; more decompositions exist.
