Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483542, here are decompositions:

71 + 31483471 = 31483542
73 + 31483469 = 31483542
89 + 31483453 = 31483542
109 + 31483433 = 31483542
113 + 31483429 = 31483542
151 + 31483391 = 31483542
173 + 31483369 = 31483542
191 + 31483351 = 31483542

Showing the first eight; more decompositions exist.
