Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536236, here are decompositions:

13 + 31536223 = 31536236
139 + 31536097 = 31536236
409 + 31535827 = 31536236
439 + 31535797 = 31536236
643 + 31535593 = 31536236
733 + 31535503 = 31536236
769 + 31535467 = 31536236
859 + 31535377 = 31536236

Showing the first eight; more decompositions exist.
