Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537694, here are decompositions:

3 + 31537691 = 31537694
7 + 31537687 = 31537694
103 + 31537591 = 31537694
151 + 31537543 = 31537694
367 + 31537327 = 31537694
421 + 31537273 = 31537694
541 + 31537153 = 31537694
547 + 31537147 = 31537694

Showing the first eight; more decompositions exist.

IPv4 address
