Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565036, here are decompositions:

7 + 31565029 = 31565036
103 + 31564933 = 31565036
109 + 31564927 = 31565036
157 + 31564879 = 31565036
163 + 31564873 = 31565036
229 + 31564807 = 31565036
313 + 31564723 = 31565036
367 + 31564669 = 31565036

Showing the first eight; more decompositions exist.
