Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504904, here are decompositions:

31 + 31504873 = 31504904
103 + 31504801 = 31504904
157 + 31504747 = 31504904
313 + 31504591 = 31504904
331 + 31504573 = 31504904
337 + 31504567 = 31504904
547 + 31504357 = 31504904
577 + 31504327 = 31504904

Showing the first eight; more decompositions exist.
