Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483636, here are decompositions:

53 + 31483583 = 31483636
59 + 31483577 = 31483636
83 + 31483553 = 31483636
89 + 31483547 = 31483636
167 + 31483469 = 31483636
179 + 31483457 = 31483636
419 + 31483217 = 31483636
467 + 31483169 = 31483636

Showing the first eight; more decompositions exist.
