Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445504, here are decompositions:

61 + 31445443 = 31445504
73 + 31445431 = 31445504
151 + 31445353 = 31445504
241 + 31445263 = 31445504
271 + 31445233 = 31445504
283 + 31445221 = 31445504
331 + 31445173 = 31445504
367 + 31445137 = 31445504

Showing the first eight; more decompositions exist.
