Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482032, here are decompositions:

19 + 31482013 = 31482032
181 + 31481851 = 31482032
331 + 31481701 = 31482032
349 + 31481683 = 31482032
409 + 31481623 = 31482032
523 + 31481509 = 31482032
601 + 31481431 = 31482032
613 + 31481419 = 31482032

Showing the first eight; more decompositions exist.
