Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527236, here are decompositions:

3 + 31527233 = 31527236
43 + 31527193 = 31527236
79 + 31527157 = 31527236
127 + 31527109 = 31527236
283 + 31526953 = 31527236
337 + 31526899 = 31527236
373 + 31526863 = 31527236
463 + 31526773 = 31527236

Showing the first eight; more decompositions exist.
