Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483678, here are decompositions:

29 + 31483649 = 31483678
101 + 31483577 = 31483678
131 + 31483547 = 31483678
449 + 31483229 = 31483678
461 + 31483217 = 31483678
509 + 31483169 = 31483678
617 + 31483061 = 31483678
701 + 31482977 = 31483678

Showing the first eight; more decompositions exist.
