Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504394, here are decompositions:

7 + 31504387 = 31504394
37 + 31504357 = 31504394
43 + 31504351 = 31504394
67 + 31504327 = 31504394
193 + 31504201 = 31504394
211 + 31504183 = 31504394
307 + 31504087 = 31504394
421 + 31503973 = 31504394

Showing the first eight; more decompositions exist.
