Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449482, here are decompositions:

3 + 31449479 = 31449482
19 + 31449463 = 31449482
61 + 31449421 = 31449482
73 + 31449409 = 31449482
79 + 31449403 = 31449482
109 + 31449373 = 31449482
193 + 31449289 = 31449482
223 + 31449259 = 31449482

Showing the first eight; more decompositions exist.
