Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532462, here are decompositions:

61 + 31532401 = 31532462
109 + 31532353 = 31532462
139 + 31532323 = 31532462
193 + 31532269 = 31532462
349 + 31532113 = 31532462
373 + 31532089 = 31532462
541 + 31531921 = 31532462
823 + 31531639 = 31532462

Showing the first eight; more decompositions exist.
