Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541360, here are decompositions:

13 + 31541347 = 31541360
79 + 31541281 = 31541360
127 + 31541233 = 31541360
181 + 31541179 = 31541360
199 + 31541161 = 31541360
313 + 31541047 = 31541360
421 + 31540939 = 31541360
439 + 31540921 = 31541360

Showing the first eight; more decompositions exist.
