Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566956, here are decompositions:

37 + 31566919 = 31566956
139 + 31566817 = 31566956
163 + 31566793 = 31566956
193 + 31566763 = 31566956
367 + 31566589 = 31566956
397 + 31566559 = 31566956
409 + 31566547 = 31566956
433 + 31566523 = 31566956

Showing the first eight; more decompositions exist.
