Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450682, here are decompositions:

61 + 31450621 = 31450682
79 + 31450603 = 31450682
103 + 31450579 = 31450682
139 + 31450543 = 31450682
199 + 31450483 = 31450682
271 + 31450411 = 31450682
313 + 31450369 = 31450682
331 + 31450351 = 31450682

Showing the first eight; more decompositions exist.
