Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620052, here are decompositions:

59 + 31619993 = 31620052
71 + 31619981 = 31620052
251 + 31619801 = 31620052
263 + 31619789 = 31620052
281 + 31619771 = 31620052
293 + 31619759 = 31620052
311 + 31619741 = 31620052
383 + 31619669 = 31620052

Showing the first eight; more decompositions exist.
