Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504488, here are decompositions:

7 + 31504481 = 31504488
101 + 31504387 = 31504488
131 + 31504357 = 31504488
137 + 31504351 = 31504488
269 + 31504219 = 31504488
359 + 31504129 = 31504488
401 + 31504087 = 31504488
557 + 31503931 = 31504488

Showing the first eight; more decompositions exist.
