Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503014, here are decompositions:

61 + 31502953 = 31503014
73 + 31502941 = 31503014
157 + 31502857 = 31503014
271 + 31502743 = 31503014
313 + 31502701 = 31503014
457 + 31502557 = 31503014
643 + 31502371 = 31503014
661 + 31502353 = 31503014

Showing the first eight; more decompositions exist.
