Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527612, here are decompositions:

29 + 31527583 = 31527612
43 + 31527569 = 31527612
71 + 31527541 = 31527612
79 + 31527533 = 31527612
89 + 31527523 = 31527612
113 + 31527499 = 31527612
131 + 31527481 = 31527612
199 + 31527413 = 31527612

Showing the first eight; more decompositions exist.
