Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483580, here are decompositions:

3 + 31483577 = 31483580
31 + 31483549 = 31483580
109 + 31483471 = 31483580
127 + 31483453 = 31483580
151 + 31483429 = 31483580
211 + 31483369 = 31483580
229 + 31483351 = 31483580
367 + 31483213 = 31483580

Showing the first eight; more decompositions exist.
