Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527608, here are decompositions:

31 + 31527577 = 31527608
67 + 31527541 = 31527608
109 + 31527499 = 31527608
127 + 31527481 = 31527608
331 + 31527277 = 31527608
397 + 31527211 = 31527608
457 + 31527151 = 31527608
499 + 31527109 = 31527608

Showing the first eight; more decompositions exist.
