Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452194, here are decompositions:

13 + 31452181 = 31452194
73 + 31452121 = 31452194
97 + 31452097 = 31452194
181 + 31452013 = 31452194
313 + 31451881 = 31452194
337 + 31451857 = 31452194
463 + 31451731 = 31452194
577 + 31451617 = 31452194

Showing the first eight; more decompositions exist.
