Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474102, here are decompositions:

29 + 31474073 = 31474102
41 + 31474061 = 31474102
59 + 31474043 = 31474102
131 + 31473971 = 31474102
239 + 31473863 = 31474102
263 + 31473839 = 31474102
293 + 31473809 = 31474102
503 + 31473599 = 31474102

Showing the first eight; more decompositions exist.
