Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504446, here are decompositions:

7 + 31504439 = 31504446
59 + 31504387 = 31504446
73 + 31504373 = 31504446
79 + 31504367 = 31504446
89 + 31504357 = 31504446
227 + 31504219 = 31504446
257 + 31504189 = 31504446
263 + 31504183 = 31504446

Showing the first eight; more decompositions exist.
