Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527404, here are decompositions:

61 + 31527343 = 31527404
127 + 31527277 = 31527404
151 + 31527253 = 31527404
157 + 31527247 = 31527404
193 + 31527211 = 31527404
211 + 31527193 = 31527404
463 + 31526941 = 31527404
523 + 31526881 = 31527404

Showing the first eight; more decompositions exist.
