Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527674, here are decompositions:

97 + 31527577 = 31527674
151 + 31527523 = 31527674
193 + 31527481 = 31527674
331 + 31527343 = 31527674
397 + 31527277 = 31527674
421 + 31527253 = 31527674
463 + 31527211 = 31527674
523 + 31527151 = 31527674

Showing the first eight; more decompositions exist.
