Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483620, here are decompositions:

23 + 31483597 = 31483620
37 + 31483583 = 31483620
43 + 31483577 = 31483620
67 + 31483553 = 31483620
71 + 31483549 = 31483620
73 + 31483547 = 31483620
127 + 31483493 = 31483620
149 + 31483471 = 31483620

Showing the first eight; more decompositions exist.
