Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504426, here are decompositions:

53 + 31504373 = 31504426
59 + 31504367 = 31504426
197 + 31504229 = 31504426
293 + 31504133 = 31504426
389 + 31504037 = 31504426
449 + 31503977 = 31504426
509 + 31503917 = 31504426
563 + 31503863 = 31504426

Showing the first eight; more decompositions exist.
