Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537192, here are decompositions:

41 + 31537151 = 31537192
59 + 31537133 = 31537192
149 + 31537043 = 31537192
191 + 31537001 = 31537192
233 + 31536959 = 31537192
419 + 31536773 = 31537192
461 + 31536731 = 31537192
563 + 31536629 = 31537192

Showing the first eight; more decompositions exist.
