Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574132, here are decompositions:

61 + 31574071 = 31574132
313 + 31573819 = 31574132
379 + 31573753 = 31574132
571 + 31573561 = 31574132
619 + 31573513 = 31574132
631 + 31573501 = 31574132
739 + 31573393 = 31574132
769 + 31573363 = 31574132

Showing the first eight; more decompositions exist.
