Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591064, here are decompositions:

3 + 31591061 = 31591064
73 + 31590991 = 31591064
157 + 31590907 = 31591064
223 + 31590841 = 31591064
331 + 31590733 = 31591064
397 + 31590667 = 31591064
433 + 31590631 = 31591064
577 + 31590487 = 31591064

Showing the first eight; more decompositions exist.
