Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453088, here are decompositions:

67 + 31453021 = 31453088
229 + 31452859 = 31453088
349 + 31452739 = 31453088
367 + 31452721 = 31453088
421 + 31452667 = 31453088
439 + 31452649 = 31453088
571 + 31452517 = 31453088
607 + 31452481 = 31453088

Showing the first eight; more decompositions exist.
