Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603112, here are decompositions:

3 + 31603109 = 31603112
103 + 31603009 = 31603112
139 + 31602973 = 31603112
181 + 31602931 = 31603112
349 + 31602763 = 31603112
421 + 31602691 = 31603112
433 + 31602679 = 31603112
439 + 31602673 = 31603112

Showing the first eight; more decompositions exist.
