Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474192, here are decompositions:

131 + 31474061 = 31474192
149 + 31474043 = 31474192
353 + 31473839 = 31474192
383 + 31473809 = 31474192
593 + 31473599 = 31474192
599 + 31473593 = 31474192
929 + 31473263 = 31474192
941 + 31473251 = 31474192

Showing the first eight; more decompositions exist.
