Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567484, here are decompositions:

73 + 31567411 = 31567484
271 + 31567213 = 31567484
331 + 31567153 = 31567484
397 + 31567087 = 31567484
691 + 31566793 = 31567484
853 + 31566631 = 31567484
937 + 31566547 = 31567484
967 + 31566517 = 31567484

Showing the first eight; more decompositions exist.
