Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523876, here are decompositions:

37 + 31523839 = 31523876
73 + 31523803 = 31523876
127 + 31523749 = 31523876
229 + 31523647 = 31523876
277 + 31523599 = 31523876
337 + 31523539 = 31523876
409 + 31523467 = 31523876
457 + 31523419 = 31523876

Showing the first eight; more decompositions exist.
