Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627592, here are decompositions:

19 + 31627573 = 31627592
109 + 31627483 = 31627592
181 + 31627411 = 31627592
331 + 31627261 = 31627592
349 + 31627243 = 31627592
523 + 31627069 = 31627592
541 + 31627051 = 31627592
613 + 31626979 = 31627592

Showing the first eight; more decompositions exist.
