Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527542, here are decompositions:

19 + 31527523 = 31527542
43 + 31527499 = 31527542
61 + 31527481 = 31527542
199 + 31527343 = 31527542
331 + 31527211 = 31527542
349 + 31527193 = 31527542
433 + 31527109 = 31527542
601 + 31526941 = 31527542

Showing the first eight; more decompositions exist.
