Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538462, here are decompositions:

13 + 31538449 = 31538462
19 + 31538443 = 31538462
211 + 31538251 = 31538462
223 + 31538239 = 31538462
331 + 31538131 = 31538462
349 + 31538113 = 31538462
409 + 31538053 = 31538462
433 + 31538029 = 31538462

Showing the first eight; more decompositions exist.
