Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603202, here are decompositions:

61 + 31603141 = 31603202
79 + 31603123 = 31603202
193 + 31603009 = 31603202
229 + 31602973 = 31603202
271 + 31602931 = 31603202
349 + 31602853 = 31603202
409 + 31602793 = 31603202
439 + 31602763 = 31603202

Showing the first eight; more decompositions exist.
