Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527194, here are decompositions:

3 + 31527191 = 31527194
37 + 31527157 = 31527194
43 + 31527151 = 31527194
241 + 31526953 = 31527194
313 + 31526881 = 31527194
331 + 31526863 = 31527194
421 + 31526773 = 31527194
463 + 31526731 = 31527194

Showing the first eight; more decompositions exist.
