Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504592, here are decompositions:

19 + 31504573 = 31504592
139 + 31504453 = 31504592
241 + 31504351 = 31504592
373 + 31504219 = 31504592
409 + 31504183 = 31504592
463 + 31504129 = 31504592
541 + 31504051 = 31504592
619 + 31503973 = 31504592

Showing the first eight; more decompositions exist.
