Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547876, here are decompositions:

37 + 31547839 = 31547876
43 + 31547833 = 31547876
127 + 31547749 = 31547876
193 + 31547683 = 31547876
337 + 31547539 = 31547876
397 + 31547479 = 31547876
463 + 31547413 = 31547876
673 + 31547203 = 31547876

Showing the first eight; more decompositions exist.
