Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504760, here are decompositions:

13 + 31504747 = 31504760
109 + 31504651 = 31504760
193 + 31504567 = 31504760
307 + 31504453 = 31504760
373 + 31504387 = 31504760
409 + 31504351 = 31504760
433 + 31504327 = 31504760
457 + 31504303 = 31504760

Showing the first eight; more decompositions exist.
