Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731178, here are decompositions:

37 + 8731141 = 8731178
67 + 8731111 = 8731178
109 + 8731069 = 8731178
139 + 8731039 = 8731178
151 + 8731027 = 8731178
229 + 8730949 = 8731178
277 + 8730901 = 8731178
331 + 8730847 = 8731178

Showing the first eight; more decompositions exist.
