Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603394, here are decompositions:

13 + 31603381 = 31603394
271 + 31603123 = 31603394
283 + 31603111 = 31603394
367 + 31603027 = 31603394
421 + 31602973 = 31603394
463 + 31602931 = 31603394
541 + 31602853 = 31603394
601 + 31602793 = 31603394

Showing the first eight; more decompositions exist.
