Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503074, here are decompositions:

13 + 31503061 = 31503074
151 + 31502923 = 31503074
193 + 31502881 = 31503074
313 + 31502761 = 31503074
331 + 31502743 = 31503074
373 + 31502701 = 31503074
487 + 31502587 = 31503074
541 + 31502533 = 31503074

Showing the first eight; more decompositions exist.
