Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603106, here are decompositions:

79 + 31603027 = 31603106
97 + 31603009 = 31603106
229 + 31602877 = 31603106
313 + 31602793 = 31603106
433 + 31602673 = 31603106
709 + 31602397 = 31603106
739 + 31602367 = 31603106
1009 + 31602097 = 31603106

Showing the first eight; more decompositions exist.
