Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485042, here are decompositions:

113 + 2147484929 = 2147485042
173 + 2147484869 = 2147485042
191 + 2147484851 = 2147485042
251 + 2147484791 = 2147485042
401 + 2147484641 = 2147485042
431 + 2147484611 = 2147485042
809 + 2147484233 = 2147485042
821 + 2147484221 = 2147485042

Showing the first eight; more decompositions exist.

IPv4 address
