Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589052, here are decompositions:

41 + 31589011 = 31589052
59 + 31588993 = 31589052
73 + 31588979 = 31589052
101 + 31588951 = 31589052
109 + 31588943 = 31589052
239 + 31588813 = 31589052
353 + 31588699 = 31589052
359 + 31588693 = 31589052

Showing the first eight; more decompositions exist.
