Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527614, here are decompositions:

31 + 31527583 = 31527614
37 + 31527577 = 31527614
73 + 31527541 = 31527614
271 + 31527343 = 31527614
337 + 31527277 = 31527614
367 + 31527247 = 31527614
421 + 31527193 = 31527614
457 + 31527157 = 31527614

Showing the first eight; more decompositions exist.
