Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592036, here are decompositions:

37 + 31591999 = 31592036
43 + 31591993 = 31592036
79 + 31591957 = 31592036
127 + 31591909 = 31592036
163 + 31591873 = 31592036
193 + 31591843 = 31592036
199 + 31591837 = 31592036
313 + 31591723 = 31592036

Showing the first eight; more decompositions exist.
