Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509052, here are decompositions:

23 + 31509029 = 31509052
53 + 31508999 = 31509052
131 + 31508921 = 31509052
401 + 31508651 = 31509052
431 + 31508621 = 31509052
503 + 31508549 = 31509052
599 + 31508453 = 31509052
821 + 31508231 = 31509052

Showing the first eight; more decompositions exist.
