Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504424, here are decompositions:

37 + 31504387 = 31504424
67 + 31504357 = 31504424
73 + 31504351 = 31504424
97 + 31504327 = 31504424
223 + 31504201 = 31504424
241 + 31504183 = 31504424
337 + 31504087 = 31504424
373 + 31504051 = 31504424

Showing the first eight; more decompositions exist.
