Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504454, here are decompositions:

67 + 31504387 = 31504454
97 + 31504357 = 31504454
103 + 31504351 = 31504454
127 + 31504327 = 31504454
151 + 31504303 = 31504454
271 + 31504183 = 31504454
367 + 31504087 = 31504454
523 + 31503931 = 31504454

Showing the first eight; more decompositions exist.
