Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503698, here are decompositions:

67 + 31503631 = 31503698
139 + 31503559 = 31503698
229 + 31503469 = 31503698
337 + 31503361 = 31503698
367 + 31503331 = 31503698
439 + 31503259 = 31503698
547 + 31503151 = 31503698
739 + 31502959 = 31503698

Showing the first eight; more decompositions exist.
