Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504952, here are decompositions:

43 + 31504909 = 31504952
79 + 31504873 = 31504952
151 + 31504801 = 31504952
379 + 31504573 = 31504952
499 + 31504453 = 31504952
601 + 31504351 = 31504952
733 + 31504219 = 31504952
751 + 31504201 = 31504952

Showing the first eight; more decompositions exist.
