Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503704, here are decompositions:

31 + 31503673 = 31503704
61 + 31503643 = 31503704
73 + 31503631 = 31503704
151 + 31503553 = 31503704
367 + 31503337 = 31503704
373 + 31503331 = 31503704
487 + 31503217 = 31503704
523 + 31503181 = 31503704

Showing the first eight; more decompositions exist.
