Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527762, here are decompositions:

53 + 31527709 = 31527762
59 + 31527703 = 31527762
61 + 31527701 = 31527762
73 + 31527689 = 31527762
103 + 31527659 = 31527762
179 + 31527583 = 31527762
193 + 31527569 = 31527762
229 + 31527533 = 31527762

Showing the first eight; more decompositions exist.
