Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603370, here are decompositions:

3 + 31603367 = 31603370
61 + 31603309 = 31603370
109 + 31603261 = 31603370
223 + 31603147 = 31603370
229 + 31603141 = 31603370
397 + 31602973 = 31603370
439 + 31602931 = 31603370
577 + 31602793 = 31603370

Showing the first eight; more decompositions exist.
