Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603454, here are decompositions:

61 + 31603393 = 31603454
73 + 31603381 = 31603454
193 + 31603261 = 31603454
307 + 31603147 = 31603454
313 + 31603141 = 31603454
331 + 31603123 = 31603454
523 + 31602931 = 31603454
577 + 31602877 = 31603454

Showing the first eight; more decompositions exist.
