Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504244, here are decompositions:

43 + 31504201 = 31504244
61 + 31504183 = 31504244
157 + 31504087 = 31504244
193 + 31504051 = 31504244
271 + 31503973 = 31504244
283 + 31503961 = 31504244
313 + 31503931 = 31504244
397 + 31503847 = 31504244

Showing the first eight; more decompositions exist.
