Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537848, here are decompositions:

5 + 31537843 = 31537848
11 + 31537837 = 31537848
101 + 31537747 = 31537848
107 + 31537741 = 31537848
127 + 31537721 = 31537848
131 + 31537717 = 31537848
157 + 31537691 = 31537848
239 + 31537609 = 31537848

Showing the first eight; more decompositions exist.
