Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506614, here are decompositions:

37 + 31506577 = 31506614
103 + 31506511 = 31506614
193 + 31506421 = 31506614
241 + 31506373 = 31506614
283 + 31506331 = 31506614
331 + 31506283 = 31506614
367 + 31506247 = 31506614
421 + 31506193 = 31506614

Showing the first eight; more decompositions exist.
