Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503722, here are decompositions:

79 + 31503643 = 31503722
163 + 31503559 = 31503722
193 + 31503529 = 31503722
379 + 31503343 = 31503722
409 + 31503313 = 31503722
463 + 31503259 = 31503722
541 + 31503181 = 31503722
571 + 31503151 = 31503722

Showing the first eight; more decompositions exist.
