Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527326, here are decompositions:

3 + 31527323 = 31527326
73 + 31527253 = 31527326
79 + 31527247 = 31527326
373 + 31526953 = 31527326
433 + 31526893 = 31527326
463 + 31526863 = 31527326
577 + 31526749 = 31527326
613 + 31526713 = 31527326

Showing the first eight; more decompositions exist.
