Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464580, here are decompositions:

3 + 31464577 = 31464580
23 + 31464557 = 31464580
71 + 31464509 = 31464580
137 + 31464443 = 31464580
179 + 31464401 = 31464580
239 + 31464341 = 31464580
311 + 31464269 = 31464580
347 + 31464233 = 31464580

Showing the first eight; more decompositions exist.
