Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536130, here are decompositions:

29 + 31536101 = 31536130
113 + 31536017 = 31536130
149 + 31535981 = 31536130
191 + 31535939 = 31536130
251 + 31535879 = 31536130
383 + 31535747 = 31536130
389 + 31535741 = 31536130
449 + 31535681 = 31536130

Showing the first eight; more decompositions exist.
