Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603048, here are decompositions:

89 + 31602959 = 31603048
131 + 31602917 = 31603048
149 + 31602899 = 31603048
359 + 31602689 = 31603048
401 + 31602647 = 31603048
461 + 31602587 = 31603048
467 + 31602581 = 31603048
509 + 31602539 = 31603048

Showing the first eight; more decompositions exist.
