Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503614, here are decompositions:

61 + 31503553 = 31503614
271 + 31503343 = 31503614
277 + 31503337 = 31503614
283 + 31503331 = 31503614
397 + 31503217 = 31503614
433 + 31503181 = 31503614
463 + 31503151 = 31503614
661 + 31502953 = 31503614

Showing the first eight; more decompositions exist.
