Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504532, here are decompositions:

79 + 31504453 = 31504532
181 + 31504351 = 31504532
229 + 31504303 = 31504532
313 + 31504219 = 31504532
331 + 31504201 = 31504532
349 + 31504183 = 31504532
571 + 31503961 = 31504532
601 + 31503931 = 31504532

Showing the first eight; more decompositions exist.
