Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523852, here are decompositions:

13 + 31523839 = 31523852
103 + 31523749 = 31523852
193 + 31523659 = 31523852
313 + 31523539 = 31523852
331 + 31523521 = 31523852
379 + 31523473 = 31523852
433 + 31523419 = 31523852
523 + 31523329 = 31523852

Showing the first eight; more decompositions exist.
