Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503626, here are decompositions:

67 + 31503559 = 31503626
73 + 31503553 = 31503626
97 + 31503529 = 31503626
157 + 31503469 = 31503626
283 + 31503343 = 31503626
313 + 31503313 = 31503626
367 + 31503259 = 31503626
397 + 31503229 = 31503626

Showing the first eight; more decompositions exist.
