Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483758, here are decompositions:

67 + 31483691 = 31483758
109 + 31483649 = 31483758
181 + 31483577 = 31483758
211 + 31483547 = 31483758
311 + 31483447 = 31483758
367 + 31483391 = 31483758
389 + 31483369 = 31483758
431 + 31483327 = 31483758

Showing the first eight; more decompositions exist.
