Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482152, here are decompositions:

109 + 31482043 = 31482152
139 + 31482013 = 31482152
241 + 31481911 = 31482152
409 + 31481743 = 31482152
421 + 31481731 = 31482152
439 + 31481713 = 31482152
631 + 31481521 = 31482152
643 + 31481509 = 31482152

Showing the first eight; more decompositions exist.
