Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527338, here are decompositions:

61 + 31527277 = 31527338
127 + 31527211 = 31527338
181 + 31527157 = 31527338
229 + 31527109 = 31527338
397 + 31526941 = 31527338
439 + 31526899 = 31527338
457 + 31526881 = 31527338
547 + 31526791 = 31527338

Showing the first eight; more decompositions exist.
