Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563332, here are decompositions:

79 + 31563253 = 31563332
139 + 31563193 = 31563332
331 + 31563001 = 31563332
349 + 31562983 = 31563332
373 + 31562959 = 31563332
421 + 31562911 = 31563332
709 + 31562623 = 31563332
739 + 31562593 = 31563332

Showing the first eight; more decompositions exist.
