Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504364, here are decompositions:

7 + 31504357 = 31504364
13 + 31504351 = 31504364
37 + 31504327 = 31504364
61 + 31504303 = 31504364
163 + 31504201 = 31504364
181 + 31504183 = 31504364
277 + 31504087 = 31504364
313 + 31504051 = 31504364

Showing the first eight; more decompositions exist.
