Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527602, here are decompositions:

19 + 31527583 = 31527602
61 + 31527541 = 31527602
79 + 31527523 = 31527602
103 + 31527499 = 31527602
349 + 31527253 = 31527602
409 + 31527193 = 31527602
661 + 31526941 = 31527602
709 + 31526893 = 31527602

Showing the first eight; more decompositions exist.
