Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627952, here are decompositions:

3 + 31627949 = 31627952
73 + 31627879 = 31627952
151 + 31627801 = 31627952
199 + 31627753 = 31627952
313 + 31627639 = 31627952
379 + 31627573 = 31627952
409 + 31627543 = 31627952
541 + 31627411 = 31627952

Showing the first eight; more decompositions exist.
