Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504136, here are decompositions:

3 + 31504133 = 31504136
7 + 31504129 = 31504136
163 + 31503973 = 31504136
283 + 31503853 = 31504136
337 + 31503799 = 31504136
409 + 31503727 = 31504136
463 + 31503673 = 31504136
577 + 31503559 = 31504136

Showing the first eight; more decompositions exist.
