Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461674, here are decompositions:

103 + 31461571 = 31461674
151 + 31461523 = 31461674
157 + 31461517 = 31461674
193 + 31461481 = 31461674
271 + 31461403 = 31461674
313 + 31461361 = 31461674
331 + 31461343 = 31461674
373 + 31461301 = 31461674

Showing the first eight; more decompositions exist.
