Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504710, here are decompositions:

7 + 31504703 = 31504710
19 + 31504691 = 31504710
43 + 31504667 = 31504710
59 + 31504651 = 31504710
103 + 31504607 = 31504710
137 + 31504573 = 31504710
163 + 31504547 = 31504710
229 + 31504481 = 31504710

Showing the first eight; more decompositions exist.
