Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527554, here are decompositions:

13 + 31527541 = 31527554
31 + 31527523 = 31527554
73 + 31527481 = 31527554
211 + 31527343 = 31527554
277 + 31527277 = 31527554
307 + 31527247 = 31527554
397 + 31527157 = 31527554
601 + 31526953 = 31527554

Showing the first eight; more decompositions exist.
