Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475762, here are decompositions:

13 + 31475749 = 31475762
79 + 31475683 = 31475762
139 + 31475623 = 31475762
151 + 31475611 = 31475762
163 + 31475599 = 31475762
181 + 31475581 = 31475762
271 + 31475491 = 31475762
421 + 31475341 = 31475762

Showing the first eight; more decompositions exist.
