Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477622, here are decompositions:

19 + 31477603 = 31477622
61 + 31477561 = 31477622
73 + 31477549 = 31477622
79 + 31477543 = 31477622
109 + 31477513 = 31477622
139 + 31477483 = 31477622
193 + 31477429 = 31477622
199 + 31477423 = 31477622

Showing the first eight; more decompositions exist.
