Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504510, here are decompositions:

17 + 31504493 = 31504510
29 + 31504481 = 31504510
71 + 31504439 = 31504510
137 + 31504373 = 31504510
281 + 31504229 = 31504510
383 + 31504127 = 31504510
593 + 31503917 = 31504510
599 + 31503911 = 31504510

Showing the first eight; more decompositions exist.
