Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504756, here are decompositions:

53 + 31504703 = 31504756
89 + 31504667 = 31504756
137 + 31504619 = 31504756
149 + 31504607 = 31504756
263 + 31504493 = 31504756
317 + 31504439 = 31504756
383 + 31504373 = 31504756
389 + 31504367 = 31504756

Showing the first eight; more decompositions exist.
