Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606124, here are decompositions:

37 + 31606087 = 31606124
73 + 31606051 = 31606124
211 + 31605913 = 31606124
313 + 31605811 = 31606124
367 + 31605757 = 31606124
397 + 31605727 = 31606124
541 + 31605583 = 31606124
547 + 31605577 = 31606124

Showing the first eight; more decompositions exist.
