Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504616, here are decompositions:

43 + 31504573 = 31504616
163 + 31504453 = 31504616
229 + 31504387 = 31504616
313 + 31504303 = 31504616
397 + 31504219 = 31504616
433 + 31504183 = 31504616
487 + 31504129 = 31504616
643 + 31503973 = 31504616

Showing the first eight; more decompositions exist.
