Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524644, here are decompositions:

3 + 31524641 = 31524644
37 + 31524607 = 31524644
103 + 31524541 = 31524644
127 + 31524517 = 31524644
241 + 31524403 = 31524644
313 + 31524331 = 31524644
367 + 31524277 = 31524644
373 + 31524271 = 31524644

Showing the first eight; more decompositions exist.
