Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529194, here are decompositions:

107 + 31529087 = 31529194
113 + 31529081 = 31529194
197 + 31528997 = 31529194
227 + 31528967 = 31529194
353 + 31528841 = 31529194
383 + 31528811 = 31529194
443 + 31528751 = 31529194
647 + 31528547 = 31529194

Showing the first eight; more decompositions exist.

IPv4 address
