Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31565044, here are decompositions:

3 + 31565041 = 31565044
53 + 31564991 = 31565044
101 + 31564943 = 31565044
191 + 31564853 = 31565044
263 + 31564781 = 31565044
383 + 31564661 = 31565044
431 + 31564613 = 31565044
653 + 31564391 = 31565044

Showing the first eight; more decompositions exist.
