Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527764, here are decompositions:

61 + 31527703 = 31527764
67 + 31527697 = 31527764
181 + 31527583 = 31527764
223 + 31527541 = 31527764
241 + 31527523 = 31527764
283 + 31527481 = 31527764
421 + 31527343 = 31527764
487 + 31527277 = 31527764

Showing the first eight; more decompositions exist.
