Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504776, here are decompositions:

29 + 31504747 = 31504776
73 + 31504703 = 31504776
109 + 31504667 = 31504776
157 + 31504619 = 31504776
229 + 31504547 = 31504776
283 + 31504493 = 31504776
337 + 31504439 = 31504776
389 + 31504387 = 31504776

Showing the first eight; more decompositions exist.
