Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540060, here are decompositions:

29 + 31540031 = 31540060
47 + 31540013 = 31540060
53 + 31540007 = 31540060
89 + 31539971 = 31540060
197 + 31539863 = 31540060
239 + 31539821 = 31540060
347 + 31539713 = 31540060
353 + 31539707 = 31540060

Showing the first eight; more decompositions exist.
