Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504794, here are decompositions:

11 + 31504783 = 31504794
47 + 31504747 = 31504794
103 + 31504691 = 31504794
127 + 31504667 = 31504794
227 + 31504567 = 31504794
313 + 31504481 = 31504794
421 + 31504373 = 31504794
443 + 31504351 = 31504794

Showing the first eight; more decompositions exist.
