Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527624, here are decompositions:

41 + 31527583 = 31527624
47 + 31527577 = 31527624
83 + 31527541 = 31527624
101 + 31527523 = 31527624
103 + 31527521 = 31527624
127 + 31527497 = 31527624
211 + 31527413 = 31527624
281 + 31527343 = 31527624

Showing the first eight; more decompositions exist.
