Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527656, here are decompositions:

73 + 31527583 = 31527656
79 + 31527577 = 31527656
157 + 31527499 = 31527656
313 + 31527343 = 31527656
379 + 31527277 = 31527656
409 + 31527247 = 31527656
463 + 31527193 = 31527656
499 + 31527157 = 31527656

Showing the first eight; more decompositions exist.
