Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504448, here are decompositions:

61 + 31504387 = 31504448
97 + 31504351 = 31504448
229 + 31504219 = 31504448
397 + 31504051 = 31504448
487 + 31503961 = 31504448
601 + 31503847 = 31504448
607 + 31503841 = 31504448
919 + 31503529 = 31504448

Showing the first eight; more decompositions exist.
