Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504146, here are decompositions:

13 + 31504133 = 31504146
17 + 31504129 = 31504146
19 + 31504127 = 31504146
43 + 31504103 = 31504146
59 + 31504087 = 31504146
109 + 31504037 = 31504146
173 + 31503973 = 31504146
229 + 31503917 = 31504146

Showing the first eight; more decompositions exist.
