Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503464, here are decompositions:

103 + 31503361 = 31503464
127 + 31503337 = 31503464
151 + 31503313 = 31503464
283 + 31503181 = 31503464
313 + 31503151 = 31503464
523 + 31502941 = 31503464
541 + 31502923 = 31503464
607 + 31502857 = 31503464

Showing the first eight; more decompositions exist.
