Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503598, here are decompositions:

29 + 31503569 = 31503598
41 + 31503557 = 31503598
89 + 31503509 = 31503598
257 + 31503341 = 31503598
389 + 31503209 = 31503598
419 + 31503179 = 31503598
431 + 31503167 = 31503598
479 + 31503119 = 31503598

Showing the first eight; more decompositions exist.
