Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503776, here are decompositions:

43 + 31503733 = 31503776
103 + 31503673 = 31503776
223 + 31503553 = 31503776
307 + 31503469 = 31503776
397 + 31503379 = 31503776
433 + 31503343 = 31503776
439 + 31503337 = 31503776
463 + 31503313 = 31503776

Showing the first eight; more decompositions exist.
