Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595436, here are decompositions:

29 + 31595407 = 31595436
43 + 31595393 = 31595436
53 + 31595383 = 31595436
73 + 31595363 = 31595436
157 + 31595279 = 31595436
163 + 31595273 = 31595436
193 + 31595243 = 31595436
199 + 31595237 = 31595436

Showing the first eight; more decompositions exist.
