Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527254, here are decompositions:

7 + 31527247 = 31527254
43 + 31527211 = 31527254
61 + 31527193 = 31527254
97 + 31527157 = 31527254
103 + 31527151 = 31527254
313 + 31526941 = 31527254
373 + 31526881 = 31527254
463 + 31526791 = 31527254

Showing the first eight; more decompositions exist.
