Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524812, here are decompositions:

3 + 31524809 = 31524812
19 + 31524793 = 31524812
139 + 31524673 = 31524812
271 + 31524541 = 31524812
313 + 31524499 = 31524812
409 + 31524403 = 31524812
541 + 31524271 = 31524812
619 + 31524193 = 31524812

Showing the first eight; more decompositions exist.
